Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Organization Wynn Resorts, Limited, a Nevada corporation (together with its subsidiaries, "Wynn Resorts" or the "Company") is a designer, developer, and operator of integrated resorts featuring luxury hotel rooms, high-end retail space, an array of dining and entertainment options, meeting and convention facilities, and gaming. In the Macau Special Administrative Region of the People's Republic of China ("Macau"), the Company owns approximately 72% of Wynn Macau, Limited ("WML"), which includes the operations of the Wynn Palace and Wynn Macau resorts. The Company refers to Wynn Palace and Wynn Macau as its Macau Operations. In Las Vegas, Nevada, the Company operates and, with the exception of certain retail space, owns 100% of Wynn Las Vegas. Additionally, the Company is a 50.1% owner and managing member of a joint venture that owns and leases certain retail space at Wynn Las Vegas (the "Retail Joint Venture"). The Company refers to Wynn Las Vegas and the Retail Joint Venture as its Las Vegas Operations. On June 23, 2019, the Company opened Encore Boston Harbor, an integrated resort in Everett, Massachusetts, that is owned 100% by the Company. In October 2020, Wynn Interactive, Ltd. ("Wynn Interactive") was formed through the merger of Wynn Resorts' digital gaming businesses and Wynn's strategic partner, BetBull Limited ("BetBull"). The merger was effected through a series of transactions which resulted in the Company contributing to BetBull its interests in WSI US, LLC and Wynn Social Gaming, LLC, which operate Wynn's existing U.S. online sports betting and gaming business and social casino business, respectively. Following the merger, Wynn Resorts holds an approximately 71% interest in Wynn Interactive, which Wynn Resorts will consolidate. Recent Developments Related to COVID-19 As previously disclosed, in January 2020, an outbreak of a new strain of coronavirus, COVID-19 ("COVID-19"), was identified. Since then, COVID-19 has spread around the world, and steps have been taken by various countries, including those in which the Company operates, to advise citizens to avoid non-essential travel, to restrict inbound international travel, to implement closures of non-essential operations, and to implement quarantines and lockdowns to contain the spread of the virus. Currently, no fully effective treatments or vaccines have been developed, and there can be no assurance as to if or when an effective treatment or vaccine will be discovered. Macau Operations In response to the COVID-19 pandemic, the Macau government announced on February 4, 2020 the closure of all casino operations in Macau, including those at Wynn Palace and Wynn Macau, for a period of 15 days. On February 20, 2020, casino operations at Wynn Palace and Wynn Macau reopened on a reduced basis and have since been fully restored; however, certain COVID-19 specific protective measures, such as traveler quarantines and requirements for negative COVID-19 tests before entering Macau, limiting the number of seats per table game, slot machine spacing, temperature checks, mask protection, COVID-19 negative test results requirements for entry to gaming areas, and health declarations remain in effect at the present time. Visitation to Macau has fallen significantly since the outbreak of COVID-19, driven by the pandemic's strong deterrent effect on travel and social activities, the suspension in late January 2020 of the Chinese government's visa and group tour schemes that allow mainland Chinese residents to travel to Macau, quarantine and testing measures in Macau and elsewhere, travel and entry requirements, restrictions, and bans in Macau, Hong Kong, Taiwan, and certain cities and regions in mainland China, and the suspension of ferry services to Macau from Hong Kong and mainland China and other modes of transportation within Macau. Regionally, bans on entry or enhanced quarantine requirements, depending on the person’s residency and their recent travel history, for any Macau residents, PRC citizens, Hong Kong residents and Taiwan residents attempting to enter Macau are drastically impacting visitation. Persons who are not residents of the Greater China area are barred from entry to Macau at this time, and quarantine requirements for those traveling between Hong Kong and Macau have been announced to remain effective until at least December 31, 2020, at which time they may be lifted. While most of the foregoing travel restrictions and quarantine requirements continue to weigh on visitation to Macau, beginning in June 2020 certain of these restrictions have eased as certain regions gradually recover from the COVID-19 pandemic. In July 2020, Guangdong Province, a Chinese province adjacent to Macau, eased certain quarantine requirements for those traveling between Guangdong Province and Macau, subject to certain testing requirements and health declarations. On September 23, 2020, mainland China authorities fully resumed the Individual Visit Scheme exit visa program, which, prior to its suspension by the PRC government due to COVID-19 travel restrictions, permitted individual PRC citizens from nearly 50 PRC cities to travel to Macau for tourism purposes. Stringent health declarations, testing and other procedures remain in place, and all visitors seeking entry to Macau need to test negative for COVID-19 before entering Macau. Las Vegas Operations and Encore Boston Harbor Wynn Las Vegas closed on March 17, 2020, and reopened on June 4, 2020 with certain COVID-19 specific protective measures in place, such as limiting the number of seats per table game, slot machine spacing, temperature checks, mask protection, and suspension of certain entertainment and nightlife offerings. Beginning October 19, 2020, Encore at Wynn Las Vegas adjusted its operating schedule to five days/four nights each week due to currently reduced customer demand levels. Encore Boston Harbor closed on March 15, 2020, and reopened on July 10, 2020 with certain COVID-19 specific protective measures in place, such as limiting the number of seats per table game, slot machine spacing, temperature checks, and mask protection. In addition, certain food and beverage outlets remain closed and hotel reservations were limited to Thursday through Sunday through the third quarter of 2020. On November 2, 2020, the Governor of Massachusetts issued a directive limiting the operating hours of certain businesses, including restaurants and casinos, effective November 6, 2020. Encore Boston Harbor has modified its hours of operation as a result of this directive. The Company is currently unable to determine when these measures will be lifted. Summary The COVID-19 pandemic has had and will continue to have an adverse effect on the Company's results of operations. The Company is currently unable to determine when protective measures in effect at our Macau Operations, Las Vegas Operations, and Encore Boston Harbor will be lifted. Given the uncertainty around the extent and timing of the potential future spread or mitigation of COVID-19 and around the imposition or relaxation of protective measures, management cannot reasonably estimate the impact to the Company's future results of operations, cash flows, or financial condition. As of September 30, 2020, the Company had total cash and cash equivalents, excluding restricted cash, of $3.55 billion, and had access to $15.9 million of available borrowing capacity from the WRF Revolving Facility. In addition, the Company has suspended its dividend program and has postponed major project capital expenditures. Given the Company's liquidity position at September 30, 2020 and the steps the Company has taken as further described in Note 6, "Long-Term Debt," the Company believes it is able to support continuing operations and respond to the current COVID-19 pandemic challenges.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures herein are adequate to make the information presented not misleading. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary to a fair presentation of the results for the interim periods presented. The results for the three and nine months ended September 30, 2020 are not necessarily indicative of results to be expected for the full fiscal year. These Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as variable interest entities ("VIEs") of which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 15, "Retail Joint Venture." All significant intercompany accounts and transactions have been eliminated. Accounts Receivable Accounts receivable, including casino and hotel receivables, are typically non-interest bearing and are recorded at amortized cost. Casino receivables primarily consist of credit issued to patrons in the form of markers and advances paid to gaming promoters. The Company issues credit based on factors such as level of play and financial resources, following background and credit checks. The casino credit extended by the Company is generally unsecured and due on demand. Gaming promoter advances are settled shortly after each month end. An estimated allowance for credit losses is maintained to reduce the Company's receivables to their carrying amount, which reflects the net amount the Company expects to collect. The allowance estimate reflects specific review of customer accounts and outstanding gaming promoter accounts with a balance over a specified dollar amount, based upon the age of the account, the customer's financial condition as well as management's experience with historical and current collection trends, current economic and business conditions, and management's expectations of future economic and business conditions and forecasts. Accounts are written off when management deems them to be uncollectible. Recoveries of accounts previously written off are recorded when received. Gaming Taxes The Company is subject to taxes based on gross gaming revenues in the jurisdictions in which it operates, subject to applicable jurisdictional adjustments. These gaming taxes are recorded as casino expenses in the accompanying Condensed Consolidated Statements of Operations. These taxes totaled $66.1 million and $543.9 million for the three months ended September 30, 2020 and 2019, respectively, and $332.5 million and $1.69 billion for the nine months ended September 30, 2020 and 2019, respectively. Recently Adopted Accounting Standards Financial Instruments - Credit Losses The FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) in 2016. The new guidance replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans and other financial instruments, the Company is required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements. Cloud Computing Arrangement Implementation Costs In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU is intended to eliminate potential diversity in practice in accounting for costs incurred to implement cloud computing arrangements that are service contracts by requiring customers in such arrangements to follow internal-use software guidance with respect to such costs, with any resulting deferred implementation costs recognized over the term of the contract in the same income statement line item as the fees associated with the hosting element of the arrangement. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The new guidance amends the disclosure requirements for recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures on fair value measurements in ASC 820. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements.

As of September 30, 2020 and December 31, 2019, approximately 79.3% and 79.0%, respectively, of the Company's markers were due from customers residing outside the United States, primarily in Asia. Business or economic conditions or other significant events in the countries in which our customers reside could affect the collectability of such receivables. The Company believes the concentration of its credit risk in casino receivables is mitigated substantially by its credit investigation process, credit policies and collection procedures. The Company’s allowance for casino credit losses was 45.8% and 12.4% of gross casino receivables as of September 30, 2020 and December 31, 2019, respectively. The increase in allowance for casino credit losses is primarily due to the impact of historical collection patterns and expectations of current and future collection trends in light of the COVID-19 pandemic, as well as the specific review of customer accounts. Although the Company believes that its allowance is adequate, it is possible the estimated amounts of cash collections with respect to receivables could change. The Company’s allowance for credit losses from its hotel and other receivables is not material. The following table shows the movement in the Company's allowance for credit losses recognized for receivables that occurred during the period (in thousands): September 30, September 30, Balance at beginning of year $ 39,317 $ 32,694 Provision for credit losses 60,548 13,039 Write-offs (1,233) (12,833) Recoveries of receivables previously written-off 228 — Effect of exchange rate 129 (19) Balance at end of period $ 98,989 $ 32,881

WML Senior Notes Offering On June 19, 2020, WML issued $750.0 million aggregate principal amount of 5 1/2% Senior Notes due 2026 (the "Existing 2026 WML Notes") pursuant to an indenture (the "2026 Indenture"). On August 26, 2020, WML issued additional $250.0 million aggregate principal amount of 5 1/2% Senior Notes due 2026 (the "Additional 2026 Notes," together with the Existing 2026 WML Notes, "2026 WML Notes") pursuant to the 2026 Indenture, and $600.0 million aggregate principal amount of 5 5/8% Senior Notes due 2028 (the "2028 WML Notes," together with the 2026 WML Notes, the “2026 and 2028 WML Notes”) pursuant to an indenture (the "2028 Indenture,” together with the 2026 Indenture, the “2026 and 2028 Indentures”). The Additional 2026 Notes have identical terms, other than the issue date and the issue price, to, rank equally with and form a part of a single class of securities with the Existing 2026 WML Notes. The 2026 WML Notes will mature on January 15, 2026 and bear interest at the rate of 5 1/2% per annum payable in arrears semi-annually on January 15 and July 15 of each year, beginning on January 15, 2021. At any time prior to June 15, 2022, WML may use the net cash proceeds from certain equity offerings to redeem up to 35% of the aggregate principal amount of the 2026 WML Notes at a redemption price equal to 105.500% of the aggregate principal amount of the 2026 WML Notes, plus accrued and unpaid interest, if any. At any time prior to June 15, 2022, WML may redeem the 2026 WML Notes in whole or in part at a redemption price equal to the greater of (a) 100% of the aggregate principal amount of the 2026 WML Notes to be redeemed, or (b) a make-whole amount as determined by an independent investment banker in accordance with the terms of the 2026 Indenture, in either case, plus accrued and unpaid interest. In addition, on or after June 15, 2022, WML may redeem the 2026 WML Notes in whole or in part at a premium decreasing annually from 104.125% of the applicable principal amount to 100.000%, plus accrued and unpaid interest. If WML undergoes a Change of Control (as defined in the 2026 Indenture), it must offer to repurchase the 2026 WML Notes at a price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest. In addition, WML may redeem the 2026 WML Notes, in whole but not in part, at a redemption price equal to 100% of the principal amount, plus accrued and unpaid interest, in response to any change in or amendment to certain tax laws or tax positions. Further, if a holder or beneficial owner of the 2026 WML Notes fails to meet certain requirements imposed by any Gaming Authority (as defined in the 2026 Indenture), WML may require the holder or beneficial owner to dispose of or redeem its 2026 WML Notes. The 2028 WML Notes will mature on August 26, 2028 and bear interest at the rate of 5 5/8% per annum payable in arrears semi-annually on February 26 and August 26 of each year, beginning on February 26, 2021. At any time prior to August 26, 2023, WML may use the net cash proceeds from certain equity offerings to redeem up to 35% of the aggregate principal amount of the 2028 WML Notes at a redemption price equal to 105.625% of the aggregate principal amount of the 2028 WML Notes, plus accrued and unpaid interest, if any. At any time prior to August 26, 2023, WML may redeem the 2028 WML Notes in whole or in part at a redemption price equal to the greater of (a) 100% of the aggregate principal amount of the 2028 WML Notes to be redeemed, or (b) a make-whole amount as determined by an independent investment banker in accordance with the terms of the 2028 Indenture, in either case, plus accrued and unpaid interest. In addition, on or after August 26, 2023, WML may redeem the 2028 WML Notes in whole or in part at a premium decreasing annually from 102.813% of the applicable principal amount to 100.000%, plus accrued and unpaid interest. If WML undergoes a Change of Control (as defined in the 2028 Indenture), it must offer to repurchase the 2028 WML Notes at a price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest. In addition, WML may redeem the 2028 WML Notes, in whole but not in part, at a redemption price equal to 100% of the principal amount, plus accrued and unpaid interest, in response to any change in or amendment to certain tax laws or tax positions. Further, if a holder or beneficial owner of the 2028 WML Notes fails to meet certain requirements imposed by any Gaming Authority (as defined in the 2028 Indenture), WML may require the holder or beneficial owner to dispose of or redeem its 2028 WML Notes. Upon the occurrence of (a) any event after which none of WML or any subsidiary of WML has the applicable gaming concessions or authorizations in Macau in substantially the same manner and scope as WML and its subsidiaries are entitled to at the date on which the 2026 and 2028 WML Notes are issued, for a period of 10 consecutive days or more, and such event has a material adverse effect on WML and its subsidiaries, taken as a whole; or (b) the termination or modification of any such concessions or authorizations which has a material adverse effect on WML and its subsidiaries, taken as a whole, each holder of the 2026 and 2028 WML Notes will have the right to require WML to repurchase all or any part of such holder’s 2026 and 2028 WML Notes at a purchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest. The 2026 and 2028 WML Notes are WML’s general unsecured obligations and rank pari passu in right of payment with all of WML’s existing and future senior unsecured indebtedness; will rank senior to all of WML’s future subordinated indebtedness, if any; will be effectively subordinated to all of WML’s future secured indebtedness to the extent of the value of the assets securing such debt; and will be structurally subordinated to all existing and future obligations of WML’s subsidiaries, including WML’s existing credit facilities. The 2026 and 2028 WML Notes are not registered under the Securities Act of 1933, as amended (the “Securities Act”), and the 2026 and 2028 WML Notes are subject to restrictions on transferability and resale. The 2026 and 2028 Indentures contain covenants limiting WML’s (and certain of its subsidiaries’) ability to, among other things: merge or consolidate with another company; transfer or sell all or substantially all of its properties or assets; and lease all or substantially all of its properties or assets. The terms of the 2026 and 2028 Indentures contain customary events of default, including, but not limited to: default for 30 days in the payment when due of interest on the 2026 and 2028 WML Notes; default in the payment when due of the principal of, or premium, if any, on the 2026 and 2028 WML Notes; failure to comply with any payment obligations relating to the repurchase by WML of the 2026 and 2028 WML Notes upon a change of control; failure to comply with certain covenants in the 2026 and 2028 Indentures; certain defaults on certain other indebtedness; failure to pay judgments against WML or certain subsidiaries that, in the aggregate, exceed $50 million; and certain events of bankruptcy or insolvency. In the case of an event of default arising from certain events of bankruptcy or insolvency, all 2026 and 2028 WML Notes then outstanding will become due and payable immediately without further action or notice. WML intends to use the net proceeds from the Existing 2026 WML Notes for general corporate purposes until WML's business recovers from the effects of the COVID-19 pandemic, and then to facilitate the repayment of a portion of the amounts outstanding under the Wynn Macau Credit Facilities. WML used the net proceeds from the Additional 2026 and 2028 WML Notes to facilitate the prepayment of term loans outstanding under the Wynn Macau Credit Facilities in September 2020. WML used a portion of the proceeds from the 2026 and 2028 WML Notes to pay related fees and expenses totaling $14.2 million, which was recorded as debt issuance costs within the Condensed Consolidated Balance Sheet. WRF 7 3/4% Senior Notes, due 2025 On April 14, 2020, WRF and its subsidiary Wynn Resorts Capital Corp. (collectively with WRF, the "WRF Issuers"), each an indirect wholly owned subsidiary of the Company, issued $600.0 million aggregate principal amount of 7 3/4% Senior Notes due 2025 (the "2025 WRF Notes") pursuant to an indenture (the "2025 Indenture") among the WRF Issuers, the guarantors party thereto, and U.S. Bank National Association, as trustee (the "Trustee"), in a private offering. The 2025 WRF Notes were issued at par. The 2025 WRF Notes will mature on April 15, 2025 and bear interest at the rate of 7 3/4% per annum payable in arrears semi-annually on April 15 and October 15 of each year, beginning on October 15, 2020. The WRF Issuers may redeem some or all of the 2025 WRF Notes at any time prior to April 15, 2022 at a redemption price equal to 100% of the aggregate principal amount of the 2025 WRF Notes to be redeemed plus a "make-whole" premium and accrued and unpaid interest. In addition, at any time prior to April 15, 2022, the WRF Issuers may, on any one or more occasions, redeem up to 35% of the original aggregate principal amount of the 2025 WRF Notes with the proceeds of one or more equity offerings at a redemption price equal to 107.75% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date. On or after April 15, 2022, the WRF Issuers may redeem some or all of the 2025 WRF Notes at the redemption prices set forth in the 2025 Indenture plus accrued and unpaid interest. In the event of a change of control triggering event, the WRF Issuers must offer to repurchase the 2025 WRF Notes at a repurchase price equal to 101% of the aggregate principal amount thereof plus any accrued and unpaid interest, to, but not including, the repurchase date. The 2025 WRF Notes are subject to disposition and redemption requirements imposed by gaming laws and regulations of applicable gaming regulatory authorities. The 2025 WRF Notes are jointly and severally guaranteed by each of WRF’s existing domestic restricted subsidiaries that guarantee indebtedness under the WRF's senior secured credit facilities and the WRF Issuers' existing 5 1/8% senior notes due 2029, including Wynn Las Vegas, LLC and each of its subsidiaries that guarantees its existing senior notes due 2023, 2025 and 2027. The 2025 Indenture contains covenants that limit the ability of the WRF Issuers and the guarantors to, among other things, enter into sale-leaseback transactions, create or incur liens to secure debt, and merge, consolidate or sell all or substantially all of the WRF Issuers' assets. These covenants are subject to exceptions and qualifications set forth in the 2025 Indenture. The 2025 Indenture also contains customary events of default, including, but not limited to, failure to make required payments, failure to comply with certain covenants, failure to pay certain other indebtedness, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the 2025 Indenture allows either the Trustee or the holders of at least 25% in aggregate principal amount of the 2025 WRF Notes, as applicable, issued under such 2025 Indenture to accelerate the amounts due under the 2025 WRF Notes, or in the case of a bankruptcy or insolvency, will automatically cause the acceleration of the amounts due under the 2025 WRF Notes. The 2025 WRF Notes were offered pursuant to an exemption under the Securities Act of 1933, as amended (the "Securities Act"). The 2025 WRF Notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act or outside the United States to certain persons in reliance on Regulation S under the Securities Act. The 2025 WRF Notes have not been and will not be registered under the Securities Act or under any state securities laws. Therefore, the WRF 2025 Notes may not be offered or sold within the United States to, or for the account or benefit of, any United States person unless the offer or sale would qualify for a registration exemption from the Securities Act and applicable state securities laws. WRF used the net proceeds from the 2025 WRF Notes offering for general corporate purposes and to pay related fees and expenses totaling $5.6 million, of which $5.2 million was recorded as debt issuance costs within the Condensed Consolidated Balance Sheet. WRF Credit Agreement Amendment On April 10, 2020, WRF and certain of its subsidiaries entered into an amendment (the "WRF Credit Agreement Amendment") to its existing credit agreement (the "WRF Credit Agreement") among Deutsche Bank AG New York Branch, as administrative agent and collateral agent, and the other lenders party thereto. The WRF Credit Agreement Amendment amends the WRF Credit Agreement to, among other things, implement a financial covenant relief period (the "Financial Covenant Relief Period") through April 1, 2021 (unless earlier terminated by WRF), implement a financial covenant increase period (the "Financial Covenant Increase Period") commencing on the first day after the expiration of the Financial Covenant Relief Period and ending on the first day of the fourth fiscal quarter after the expiration of the Financial Covenant Relief Period (unless earlier terminated by WRF), amend the definition of "Consolidated EBITDA" in the WRF Credit Agreement during the Financial Covenant Increase Period, amend WRF's financial reporting obligations (including extensions to certain deadlines), add certain restrictions on restricted payments (including restrictions on a portion of dividends received from WRF's subsidiaries) during the Financial Covenant Relief Period and the Financial Covenant Increase Period, and amend the definition of "Material Adverse Effect" in the WRF Credit Agreement to take into consideration COVID-19. During the Financial Covenant Relief Period, the existing consolidated first lien net leverage ratio financial covenant will be replaced with a minimum liquidity financial covenant that requires WRF and its restricted subsidiaries to maintain liquidity of at least $300.0 million at all times (with liquidity being the sum of unrestricted operating cash, as defined in the WRF Credit Agreement, and the available borrowing capacity under the WRF Revolver). Following the Financial Covenant Relief Period and for as long as the Financial Covenant Increase Period is in effect, WRF may not permit the consolidated first lien net leverage ratio as of the last day of any fiscal quarter to exceed for the first fiscal quarter of the Financial Covenant Increase Period, 4.50 to 1.00, for the second fiscal quarter of the Financial Covenant Increase Period, 4.25 to 1.00, for the third fiscal quarter of the Financial Covenant Increase Period, 4.00 to 1.00, and for each subsequent fiscal quarter thereafter (including from and including the first fiscal quarter during which the Financial Covenant Increase Period has been terminated by WRF), 3.75 to 1.00. Retail Term Loan Agreement Amendment On May 5, 2020, Wynn/CA Plaza Property Owner, LLC and Wynn/CA Property Owner, LLC (collectively, the "Retail Borrowers"), subsidiaries of the Retail Joint Venture, entered into an amendment (the "Retail Term Loan Agreement Amendment") to its existing retail term loan agreement (the "Retail Term Loan Agreement"). The Retail Term Loan Agreement Amendment amends the Retail Term Loan Agreement to, among other things, temporarily suspend the requirement to maintain certain financial ratios to avoid triggering excess cash sweep provisions from the first quarter of 2020 through the fourth quarter of 2021. Debt Covenant Compliance As of September 30, 2020, management believes the Company was in compliance with all debt covenants.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax expense of $407.4 million and $19.7 million for the three months ended September 30, 2020 and 2019, respectively, and an income tax expense of $564.1 million and $19.4 million for the nine months ended September 30, 2020 and 2019. The 2020 income tax expense primarily related to the increase in the valuation allowances for U.S foreign tax credits, U.S. loss carryforwards and other U.S. deferred tax assets. The 2019 income tax expense primarily related to the increase in the valuation allowance for U.S. foreign tax credits. The Company records valuation allowances on certain of its U.S. and foreign deferred tax assets. During the third quarter of 2020, the Company concluded it could no longer rely on forecasted future taxable income in assessing a valuation allowance on its deferred tax assets. This conclusion was reached due to cumulative operating losses incurred by the Company and recent tax legislation that reduced future sources of taxable income. As of September 30, 2020, the Company now relies solely on the reversal of net taxable temporary differences in its establishment of a valuation allowance. Wynn Macau SA received a five year exemption from Macau's 12% Complementary Tax on casino gaming profits through December 31, 2020. Accordingly, for the three months ended September 30, 2019, the Company was exempt from the payment of such taxes totaling $13.4 million. For the nine months ended September 30, 2019, the Company was exempt from the payment of such taxes totaling $56.0 million. For the three and nine months ended September 30, 2020, the Company did not have any casino gaming profits exempt from the Macau Complementary Tax. The Company's non-gaming profits remain subject to the Macau Complementary Tax and its casino winnings remain subject to the Macau special gaming tax and other levies in accordance with its concession agreement. In April 2020, Wynn Macau SA received an extension of the exemption from Macau’s 12% Complementary Tax on casino gaming profits earned from January 1, 2021 to June 26, 2022, the expiration date of the gaming concession agreement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In addition to the actions noted below, the Company and its affiliates are involved in litigation arising in the normal course of business. In the opinion of management, such litigation is not expected to have a material effect on the Company's financial condition, results of operations, and cash flows. Massachusetts Gaming License Related Actions On September 17, 2014, the Massachusetts Gaming Commission ("MGC") designated Wynn MA the award winner of the Greater Boston (Region A) gaming license (the "Boston area license"). On November 7, 2014, the gaming license became effective. Revere Action On October 16, 2014, the City of Revere, the host community to the unsuccessful bidder for the Boston area license, the International Brotherhood of Electrical Workers, Local 103, and several individuals, filed a complaint against the MGC and its gaming commissioners in Suffolk Superior Court in Boston, Massachusetts (the "Revere Action"). Mohegan Sun ("Mohegan") the other applicant for the Boston area license, joined the lawsuit and challenged the MGC's award of the Boston area license. On December 3, 2015, the court granted the MGC's motion to dismiss the claims asserted in the Revere Action and the court dismissed all claims except Mohegan's claim alleging procedural error by the MGC in granting the license to Wynn MA. The plaintiffs appealed. After multiple appeals and cross appeals, only two claims remained: (1) individual plaintiffs' claim for violation of the open meeting laws; and (2) Mohegan's claim for procedural error. On July 12, 2019, the Suffolk Superior Court granted the MGC's motion for summary judgment and dismissed the open meeting law claim, leaving only Mohegan's procedural claim. On August 2, 2019, Mohegan filed a motion to file a second amended complaint, to add new claims related to the MGC's allegedly inadequate 2013 investigation. On October 15, 2019, the court granted Mohegan's motion to amend and allowed it to file a second amended intervenor's complaint. Wynn MA was not named in the Revere Action. Derivative Litigation A number of stockholder derivative actions have been filed in state and federal court located in Clark County, Nevada against certain current and former members of the Company's Board of Directors and, in some cases, the Company's current and former officers. Each of the complaints alleges, among other things, breach of fiduciary duties in failing to detect, prevent and remedy alleged inappropriate personal conduct by Stephen A. Wynn in the workplace. On September 19, 2018, the Board established a Special Litigation Committee (the "SLC") to investigate the allegations in the State Derivative Case (as defined below). The actions filed in the Eighth Judicial District Court of Clark County, Nevada were consolidated as In re Wynn Resorts, Ltd. Derivative Litigation ("State Derivative Case"). On October 26, 2018, the SLC filed a motion to intervene and stay the State Derivative Case pending completion of its investigation, which the court granted. On June 3, 2019, a separate stockholder derivative action was filed in the Eighth Judicial District Court of Clark County, Nevada alleging substantially similar causes of action as the State Derivative Case with the additional allegation that various of the Company's attorneys committed professional malpractice, and certain current and former executives also breached fiduciary duties and aided and abetted the breach of fiduciary duties, in connection with the alleged inappropriate personal conduct by Stephen A. Wynn in the workplace. On July 26, 2019, the plaintiff voluntarily dismissed Matt Maddox, Stephen A. Wynn, Kimmarie Sinatra, John J. Hagenbuch, Ray R. Irani, Jay L. Johnson, Robert J. Miller, Patricia Mulroy, Clark T. Randt, Jr., Alvin V. Shoemaker, J. Edward Virtue, D. Boone Wayson, and one of the Company's law firms from the action. On September 19, 2019, the court entered an order consolidating this action into the State Derivative Case, and on December 2, 2019, further clarified that this action may not proceed as a separate action apart from the State Derivative Case. On November 27, 2019, the State Derivative Case parties agreed to terms of a settlement agreement. The court approved the settlement agreement on February 12, 2020, and entered a written order approving the settlement on March 10, 2020. Following dismissal of the only appeal, the settlement agreement has now become effective and final. Following the dismissal, the Company has received net proceeds of $30.2 million, which has been recognized as a reduction of general and administrative expense within the accompanying Condensed Consolidated Statements of Operations for the nine months ended September 30, 2020. In 2018, several actions filed in the United States District Court, District of Nevada were consolidated as In re Wynn Resorts, Ltd. Derivative Litigation ("Federal Derivative Case"), which also claim corporate waste and violation of Section 14(a) of the Exchange Act. In June 2018, the Company filed a motion to dismiss and a motion to stay pending resolution of the Securities Action (described below). On March 29, 2019, the Court granted the Company's request for a stay. On March 25, 2020, the parties stipulated to dismiss the Federal Derivative Case given the approved settlement in the State Derivative Case. On March 25, 2019, a separate stockholder derivative action was filed in the United States District Court, District of Nevada alleging identical causes of action as the Federal Derivative Case with the additional allegation that the Board of Directors improperly refused the stockholder's demand to commence litigation against the officers and directors of the Company. On June 10, 2019, the Company filed a motion to dismiss, or alternatively to consolidate this action into the Federal Derivative Case. On March 23, 2020, the court denied the Company’s motion to dismiss as moot given the approved settlement in the State Derivative Case. On April 30, 2020, the Company filed a motion for summary judgment, seeking dismissal of the claims given the approved settlement in the State Derivative Case. Each of the actions seeks to recover for the Company unspecified damages, including restitution and disgorgement of profits, and also seeks to recover attorneys' fees, costs and related expenses for the plaintiff. Individual Stockholder Actions A number of stockholders filed individual actions in the Eighth Judicial District Court of Clark County, Nevada against certain current and former members of the Company's Board of Directors and certain of the Company's current and former officers ("Individual Stockholder Actions"). Each of the complaints alleged that defendants, among other things, breached their fiduciary duties in failing to detect, prevent and remedy alleged inappropriate personal conduct by Stephen A. Wynn in the workplace causing injury to each of the individual stockholders. On January 29, 2019, the defendants filed motions to dismiss each of the Individual Stockholder Actions. On December 12, 2019, the district court entered an order denying the motions to dismiss, which the defendants appealed to the Nevada Supreme Court on December 24, 2019. On July 27, 2020, the Supreme Court issued an order mandating that the district court dismiss the action. As of September 2, 2020, all of the Individual Stockholder Actions have been dismissed. Securities Action On February 20, 2018, a putative securities class action was filed against the Company and certain current and former officers of the Company in the United States District Court, Southern District of New York (which was subsequently transferred to the United States District Court, District of Nevada) by John V. Ferris and Joann M. Ferris on behalf of all persons who purchased the Company's common stock between February 28, 2014 and January 25, 2018. The complaint alleges, among other things, certain violations of federal securities laws and seeks to recover unspecified damages as well as attorneys' fees, costs and related expenses for the plaintiffs. On April 15, 2019, the Company filed a motion to dismiss, which the court granted on May 27, 2020, with leave to amend. On July 1, 2020, the plaintiffs filed an amended complaint. On August 14, 2020, the Company filed a motion to dismiss the amended complaint, which is pending decision from the court. The defendants in these actions will vigorously defend against the claims pleaded against them. These actions are in preliminary stages and management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of these actions or the range of reasonably possible loss, if any.

Management uses Adjusted Property EBITDA as a measure of the operating performance of its segments and to compare the operating performance of its properties with those of its competitors, as well as a basis for determining certain incentive compensation. We also present Adjusted Property EBITDA because it is used by some investors to measure a company's ability to incur and service debt, make capital expenditures and meet working capital requirements. Gaming companies have historically reported EBITDA as a supplement to GAAP. In order to view the operations of their casinos on a more stand-alone basis, gaming companies, including us, have historically excluded from their EBITDA calculations preopening expenses, property charges, corporate expenses and stock-based compensation, that do not relate to the management of specific casino properties. However, Adjusted Property EBITDA should not be considered as an alternative to operating income as an indicator of our performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure determined in accordance with GAAP. Unlike net income, Adjusted Property EBITDA does not include depreciation or interest expense and therefore does not reflect current or future capital expenditures or the cost of capital. We have significant uses of cash flows, including capital expenditures, interest payments, debt principal repayments, income taxes and other non-recurring charges, which are not reflected in Adjusted Property EBITDA. Also, our calculation of Adjusted Property EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited. (3) For the nine months ended September 30, 2020, includes a $30.2 million net gain recorded in relation to a derivative litigation settlement. For the nine months ended September 30, 2019, includes a $35.0 million nonrecurring regulatory expense. (4) Excludes $0.7 million included in pre-opening expenses for the nine months ended September 30, 2019.

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of ConsolidationThe accompanying condensed consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and entities the Company identifies as variable interest entities ("VIEs") of which the Company is determined to be the primary beneficiary. For information on the Company's VIEs, see Note 15, "Retail Joint Venture." All significant intercompany accounts and transactions have been eliminated.
Gaming Taxes	Gaming TaxesThe Company is subject to taxes based on gross gaming revenues in the jurisdictions in which it operates, subject to applicable jurisdictional adjustments. These gaming taxes are recorded as casino expenses in the accompanying Condensed Consolidated Statements of Operations.
Accounts Receivable	Accounts Receivable Accounts receivable, including casino and hotel receivables, are typically non-interest bearing and are recorded at amortized cost. Casino receivables primarily consist of credit issued to patrons in the form of markers and advances paid to gaming promoters. The Company issues credit based on factors such as level of play and financial resources, following background and credit checks. The casino credit extended by the Company is generally unsecured and due on demand. Gaming promoter advances are settled shortly after each month end. An estimated allowance for credit losses is maintained to reduce the Company's receivables to their carrying amount, which reflects the net amount the Company expects to collect. The allowance estimate reflects specific review of customer accounts and outstanding gaming promoter accounts with a balance over a specified dollar amount, based upon the age of the account, the customer's financial condition as well as management's experience with historical and current collection trends, current economic and business conditions, and management's expectations of future economic and business conditions and forecasts. Accounts are written off when management deems them to be uncollectible. Recoveries of accounts previously written off are recorded when received.
Recently Issued and Adopted Accounting Standards	Recently Adopted Accounting Standards Financial Instruments - Credit Losses The FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) in 2016. The new guidance replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans and other financial instruments, the Company is required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements. Cloud Computing Arrangement Implementation Costs In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU is intended to eliminate potential diversity in practice in accounting for costs incurred to implement cloud computing arrangements that are service contracts by requiring customers in such arrangements to follow internal-use software guidance with respect to such costs, with any resulting deferred implementation costs recognized over the term of the contract in the same income statement line item as the fees associated with the hosting element of the arrangement. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The new guidance amends the disclosure requirements for recurring and nonrecurring fair value measurements by removing, modifying, and adding certain disclosures on fair value measurements in ASC 820. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted the guidance effective January 1, 2020, and this adoption did not have a material effect on its Condensed Consolidated Financial Statements.

For more information on leases, see Note 13, "Leases". (2) "Adjusted Property EBITDA" is net income (loss) before interest, income taxes, depreciation and amortization, pre-opening expenses, property charges and other, management and license fees, corporate expenses and other (including intercompany golf course and water rights leases), stock-based compensation, change in derivatives fair value, loss on extinguishment of debt, and other non-operating income and expenses. Adjusted Property EBITDA is presented exclusively as a supplemental disclosure because management believes that it is widely used to measure the performance, and as a basis for valuation, of gaming companies. Management uses Adjusted Property EBITDA as a measure of the operating performance of its segments and to compare the operating performance of its properties with those of its competitors, as well as a basis for determining certain incentive compensation. We also present Adjusted Property EBITDA because it is used by some investors to measure a company's ability to incur and service debt, make capital expenditures and meet working capital requirements. Gaming companies have historically reported EBITDA as a supplement to GAAP. In order to view the operations of their casinos on a more stand-alone basis, gaming companies, including us, have historically excluded from their EBITDA calculations preopening expenses, property charges, corporate expenses and stock-based compensation, that do not relate to the management of specific casino properties. However, Adjusted Property EBITDA should not be considered as an alternative to operating income as an indicator of our performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure determined in accordance with GAAP. Unlike net income, Adjusted Property EBITDA does not include depreciation or interest expense and therefore does not reflect current or future capital expenditures or the cost of capital. We have significant uses of cash flows, including capital expenditures, interest payments, debt principal repayments, income taxes and other non-recurring charges, which are not reflected in Adjusted Property EBITDA.
