Organization and Basis of Presentation	Organization and Basis of Presentation
	Organization
	Hilton Worldwide Holdings Inc. ("Hilton" together with its subsidiaries, "we," "us," "our," the "Company" or the "Parent"), a Delaware corporation, is one of the largest hospitality companies in the world based upon the number of hotel rooms and timeshare units under our 12 distinct brands. We are engaged in owning, leasing, managing, developing and franchising hotels, resorts and timeshare properties. As of March 31, 2015, we owned, leased, managed or franchised 4,318 hotel and resort properties, totaling 713,883 rooms in 94 countries and territories, as well as 44 timeshare properties comprising 6,818 units.
	As of March 31, 2015, affiliates of The Blackstone Group L.P. ("Blackstone" or "our Sponsor") beneficially owned approximately 55.2 percent of our common stock.
	Basis of Presentation and Use of Estimates
	The accompanying condensed consolidated financial statements for the three months ended March 31, 2015 and 2014 have been prepared in accordance with United States of America ("U.S.") generally accepted accounting principles ("GAAP") and are unaudited. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP. Although we believe the disclosures made are adequate to prevent the information presented from being misleading, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and, accordingly, ultimate results could differ from those estimates. Interim results are not necessarily indicative of full year performance.
	In our opinion, the accompanying condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All material intercompany transactions have been eliminated in consolidation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

	Adopted Accounting Standards
	In January 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-01 ("ASU 2015-01"), Income Statement-Extraordinary and Unusual Items (Subtopic 225-20). This ASU eliminates the concept of extraordinary items and the related income statement presentation of such items. The provisions of ASU 2015-01 are effective for reporting periods beginning after December 15, 2015. We elected, as permitted by the standard, to early adopt ASU 2015-01 on a prospective basis as of January 1, 2015. The adoption did not have an effect on our condensed consolidated financial statements.
	Accounting Standards Not Yet Adopted
	In April 2015, the FASB issued ASU No. 2015-03 ("ASU 2015-03"), Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset, which is consistent with the presentation of debt discounts or premiums. The provisions of ASU 2015-03 are effective for reporting periods beginning after December 31, 2015; early adoption is permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.
	In February 2015, the FASB issued ASU No. 2015-02 ("ASU 2015-02"), Consolidation (Topic 810) - Amendments to the Consolidation Analysis. This ASU modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The provisions of ASU 2015-02 are effective for reporting periods beginning after December 15, 2015; early adoption is permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15 ("ASU 2014-15"), Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This ASU requires management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements issue date. The provisions of ASU 2014-15 are effective for reporting periods beginning after December 15, 2016; early adoption is permitted. The adoption of this ASU is not expected to have a material effect on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers (Topic 606). This ASU supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)," and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The provisions of ASU 2014-09 are effective for reporting periods beginning after December 15, 2016 and are to be applied retrospectively; early adoption is not permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.

Acquisitions Disclosure [Abstract]
Acquisitions	Acquisitions
	In February 2015, we used proceeds from the sale of the Waldorf Astoria New York (see Note 4: "Disposals") to acquire, as part of a tax deferred exchange of real property, the following properties from sellers affiliated with Blackstone for a total purchase price of $1.76 billion:
	•	the resort complex consisting of the Waldorf Astoria Orlando and the Hilton Orlando Bonnet Creek in Orlando, Florida (the "Bonnet Creek Resort");
	•	the Casa Marina Resort in Key West, Florida;
	•	the Reach Resort in Key West, Florida; and
	•	the Parc 55 hotel in San Francisco, California.
	We incurred transaction costs of $19 million recognized in other gain (loss), net in our condensed consolidated statement of operations for the three months ended March 31, 2015.
	As of the acquisition date, the fair value of the assets and liabilities acquired were as follows:
		(in millions)
	Cash and cash equivalents	$	16
	Restricted cash and cash equivalents	8
	Inventories	1
	Prepaid expenses	3
	Other current assets	1
	Property and equipment	1,756
	Other intangible assets, net	4
	Accounts payable, accrued expenses and other	(25		)
	Long-term debt	(450		)
	Net assets acquired	$	1,314
	The fair value of net assets acquired are subject to adjustments as additional information relative to the fair value at the acquisition date become available through the measurement period, which can extend for up to one year after the acquisition date. See Note 11: "Fair Value Measurements" for additional details on the fair value techniques and inputs used for the measurement of the assets and liabilities.
	The results of operations from these properties included in the condensed consolidated statement of operations for the three months ended March 31, 2015 following the acquisitions were not material.

	In February 2015, we completed the sale of the Waldorf Astoria New York for a purchase price of $1.95 billion and we repaid in full the existing mortgage loan secured by our Waldorf Astoria New York property (the "Waldorf Astoria Loan") of approximately $525 million. As a result of this repayment, we recognized a loss of $6 million in other gain (loss), net in our condensed consolidated statement of operations for the three months ended March 31, 2015 related to the reduction of the Waldorf Astoria Loan's remaining carrying amount of debt issuance costs. Additionally, the Waldorf Astoria New York property was considered a business within our ownership segment; therefore, we reduced the carrying amount of our goodwill and reduced the gain recognized on sale by $185 million, the amount representing the fair value of the business disposed of relative to the portion of our ownership reporting unit goodwill that was retained. As a result of the sale, we recognized a gain of $146 million included in gain on sales of assets, net in our condensed consolidated statement of operations for the three months ended March 31, 2015.

Consolidated Variable Interest Entities	Consolidated Variable Interest Entities
	As of March 31, 2015 and December 31, 2014, we consolidated five variable interest entities ("VIEs"). During the three months ended March 31, 2015 and 2014, we did not provide any financial or other support to any VIEs that we were not previously contractually required to provide, nor do we intend to provide such support in the future.
	Two of our VIEs lease hotels from unconsolidated affiliates in Japan. We hold a significant ownership interest in these VIEs and have the power to direct the activities that most significantly affect their economic performance. Our condensed consolidated balance sheets included the assets and liabilities of these entities, which primarily comprised the following:
		March 31,		December 31,
		2015		2014
		(in millions)
	Cash and cash equivalents	$	28	$	26
	Property and equipment, net	49		49
	Non-recourse debt	236		237
	The assets of these entities are only available to settle the obligations of these entities. Interest expense related to the non-recourse debt of these two consolidated VIEs was $5 million during the three months ended March 31, 2015 and 2014 and was included in interest expense in our condensed consolidated statements of operations.
	We have two VIEs associated with our securitization transactions that both issued debt (collectively, "Securitized Timeshare Debt"). We are the primary beneficiaries of these VIEs as we have the power to direct the activities that most significantly affect their economic performance, the obligation to absorb their losses and the right to receive benefits that are significant to them. Our condensed consolidated balance sheets included the assets and liabilities of these entities, which primarily comprised the following:
		March 31,		December 31,
		2015		2014

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	During the three months ended March 31, 2015 and 2014, derivatives were used to hedge the interest rate risk associated with variable-rate debt. Certain of our loan agreements require us to hedge interest rate risk using derivative instruments.
	During the three months ended March 31, 2015, derivatives were also used to hedge foreign exchange risk associated with certain foreign currency denominated cash balances.
	Cash Flow Hedges
	As of March 31, 2015, we held four interest rate swaps with an aggregate notional amount of $1.45 billion, which swap three-month LIBOR on the Term Loans to a fixed rate of 1.87 percent and expire in October 2018. We elected to designate these interest rate swaps as cash flow hedges for accounting purposes.
	Non-designated Hedges
	As of March 31, 2015, we held 24 short-term foreign exchange forward contracts in the notional amount of $79 million to offset exposure to fluctuations in our foreign currency denominated cash balances. We elected not to designate these foreign exchange forward contracts as hedging instruments.
	As of March 31, 2015, we held the following interest rate caps:
	•	one interest rate cap in the notional amount of $875 million, for the variable-rate component of the CMBS Loan, that expires in November 2015 and caps one-month LIBOR at 6.0 percent;
	•	one interest rate cap in the notional amount of $525 million that expires in November 2015 and caps one-month LIBOR at 4.0 percent; and
	•	one interest rate cap in the notional amount of $338 million that expires in May 2015 and caps one-month LIBOR at 3.0 percent on the Bonnet Creek Loan.
	We did not elect to designate any of these interest rate caps as hedging instruments.

	(2)	Excludes capital lease obligations of consolidated VIEs with a carrying value of $213 million and $216 million as of March 31, 2015 and December 31, 2014, respectively, and non-recourse debt of consolidated VIEs with a carrying value of $35 million and $32 million, respectively.
	We believe the carrying amounts of our other financial assets and liabilities approximated fair value as of March 31, 2015 and December 31, 2014. Our estimates of the fair values were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop the estimated fair values.
	Cash equivalents and restricted cash equivalents primarily consisted of short-term interest-bearing money market funds with maturities of less than 90 days, time deposits and commercial paper. The estimated fair values were based on available market pricing information of similar financial instruments.
	The estimated fair values of our timeshare financing receivables were based on the expected future cash flows discounted at risk-adjusted rates. The primary sensitivity in these calculations is based on the selection of appropriate discount rates. Fluctuations in these assumptions will result in different estimates of fair value. An increase in the discount rate would result in a decrease in the fair values.
	We measure our interest rate swaps at fair value, which were estimated using an income approach. The primary inputs into our fair value estimate include interest rates and yield curves based on observable market inputs of similar instruments.
	The estimated fair values of our Level 1 long-term debt were based on prices in active debt markets. The estimated fair values of certain of our Level 3 fixed-rate and variable-rate long-term debt were based on the expected future cash flows discounted at risk-adjusted rates. The primary sensitivity in these estimates is based on the selection of appropriate discount rates. Fluctuations in these assumptions will result in different estimates of fair value. An increase in the discount rate would result in a decrease in the fair values. The carrying amounts of certain of our Level 3 variable-rate long-term debt and our Level 3 variable-rate non-recourse debt approximated fair value as the interest rates under the loan agreements approximated current market rates. The estimated fair values of certain of our Level 3 variable-rate long-term debt and our Level 3 fixed-rate non-recourse debt were primarily based on indicative quotes received for similar issuances.
	As a result of our acquisition of certain properties during the three months ended March 31, 2015, we measured financial and nonfinancial assets at fair value on a nonrecurring basis (see Note 3: "Acquisitions"), as follows:
		Fair Value(1)
		(in millions)
	Property and equipment	$	1,756
	Long-term debt	450
	____________
	(1)	Fair value measurements using significant unobservable inputs (Level 3).
	We estimated the fair value of the property and equipment using discounted cash flow analysis, with an estimated stabilized growth rate of 3 percent to 4 percent, discounted cash flow terms ranging from 10 years to 11 years, a terminal capitalization rate of 7 percent to 8 percent and a discount rate of 9 percent to 10 percent. The discount and terminal capitalization rates used for the fair value of the assets reflect the risk profile of the individual markets where the assets are located and are not necessarily indicative of our hotel portfolio as a whole.
	The fair value of the long-term debt assumed was estimated based on the expected future cash flows discounted at a risk-adjusted rate of one-month LIBOR plus 275 basis points.
	No financial or nonfinancial assets were measured at fair value on a nonrecurring basis as of or for the three months ended March 31, 2014.

Income_Taxes

Income Taxes	3 Months Ended
	Mar. 31, 2015
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	At the end of each quarter we estimate the effective tax rate expected to be applied for the full year. The effective income tax rate is determined by the level and composition of pre-tax income or loss, which is subject to federal, foreign, state and local income taxes. The annual effective tax rate expected to be applied for the full year is higher than our statutory tax rate primarily because no tax benefit was recognized for the reduction of goodwill in connection with the sale of the Waldorf Astoria New York (see Note 4: "Disposals" for further information). The higher effective tax rate, as compared to our statutory tax rate, for the three months ended March 31, 2015, was largely attributable to the reduction of goodwill in connection with the sale of the Waldorf Astoria New York and losses incurred by certain foreign subsidiaries for which no tax benefits were recognized. In addition, a foreign jurisdiction where we had deferred tax assets reduced its statutory tax rate, resulting in a reduction to the deferred tax asset and a corresponding recognition of income tax expense of $6 million.
	Our total unrecognized tax benefits as of March 31, 2015 and December 31, 2014 were $401 million. We had accrued approximately $25 million and $22 million for the payment of interest and penalties as of March 31, 2015 and December 31, 2014, respectively. We recognize interest and penalties accrued related to unrecognized tax benefits in income tax expense.
	As a result of the expected resolution of examination issues with federal, state and foreign tax authorities, we believe it is reasonably possible that during the next 12 months the amount of unrecognized tax benefits will decrease up to $25 million. Included in the balance of unrecognized tax benefits as of March 31, 2015 and December 31, 2014 were $369 million and $367 million, respectively, associated with positions that, if favorably resolved, would provide a benefit to our effective tax rate.
	We file income tax returns, including returns for our subsidiaries, with federal, state and foreign jurisdictions. We are under regular and recurring audit by the IRS and other taxing authorities on open tax positions. The timing of the resolution of tax audits is highly uncertain, as are the amounts, if any, that may ultimately be paid upon such resolution. Changes may result from the conclusion of ongoing audits, appeals or litigation in state, local, federal and foreign tax jurisdictions or from the resolution of various proceedings between the U.S. and foreign tax authorities. We are no longer subject to U.S. federal income tax examination for years through 2004. As of March 31, 2015, we remain subject to federal examinations from 2005-2013, state examinations from 1999-2013 and foreign examinations of our income tax returns for the years 1996 through 2014.
	In April 2014, we received 30-day Letters from the IRS and the Revenue Agents Report ("RAR") for the 2006 and October 2007 tax years. We disagreed with several of the proposed adjustments in the RAR, filed a formal appeals protest with the IRS and did not make any tax payments related to this audit. The issues being protested in appeals relate to assertions by the IRS that: (1) certain foreign currency-denominated, intercompany loans from our foreign subsidiaries to certain U.S. subsidiaries should be recharacterized as equity for U.S. federal income tax purposes and constitute deemed dividends from such foreign subsidiaries to our U.S. subsidiaries; (2) in calculating the amount of U.S. taxable income resulting from our Hilton HHonors guest loyalty program, we should not reduce gross income by the estimated costs of future redemptions, but rather such costs would be deductible at the time the points are redeemed; and (3) certain foreign-currency denominated loans issued by one of our Luxembourg subsidiaries whose functional currency is USD, should instead be treated as issued by one of our Belgian subsidiaries whose functional currency is the Euro, and thus foreign currency gains and losses with respect to such loans should have been measured in Euros, instead of USD. In total, the proposed adjustments sought by the IRS would result in additional U.S. federal tax owed of approximately $696 million, excluding interest and penalties and potential state income taxes. The portion of this amount related to our Hilton HHonors guest loyalty program would result in a decrease to our future tax liability when the points are redeemed. We disagree with the IRS's position on each of these assertions and intend to vigorously contest them. We plan to pursue all available administrative remedies, and if we are not able to resolve these matters administratively, we plan to pursue judicial remedies. Accordingly, as of March 31, 2015, no accrual has been made for these amounts.
	State income tax returns are generally subject to examination for a period of three to five years after filing the respective return; however, the state effect of any federal tax return changes remains subject to examination by various states for a period generally of up to one year after formal notification to the states. The statute of limitations for the foreign jurisdictions generally ranges from three to ten years after filing the respective tax return.

	We sponsor multiple domestic and international employee benefit plans. Benefits are based upon years of service and compensation.
	We have a noncontributory retirement plan in the U.S. (the "Domestic Plan"), which covers certain employees not earning union benefits. This plan was frozen for participant benefit accruals in 1996. We also have multiple employee benefit plans that cover many of our international employees. These include a plan that covers workers in the United Kingdom (the "U.K. Plan"), which was frozen to further accruals in November 2013, and a number of smaller plans that cover workers in various other countries around the world (the "International Plans").

	In February 2012, we were required to post a bond of $76 million under a class action lawsuit against Hilton and the Domestic Plan to support potential future plan contributions from us. We were required by our insurers to fund a cash account as collateral for the bond. In November 2014, $57 million of the cash collateral was released to us based on the requirements of our insurer, and as of March 31, 2015, $19 million that remained in the account was classified as restricted cash and cash equivalents in our condensed consolidated balance sheet. In February 2015, the bond was ordered to be released, and we expect to receive the remaining cash collateral during 2015.

	Under the Hilton Worldwide Holdings Inc. 2013 Omnibus Incentive Plan (the "Stock Plan"), we issue time-vesting restricted stock units ("RSUs"), nonqualified stock options ("options") and performance-vesting restricted stock units and restricted stock (collectively, "performance shares").
	We recognized share-based compensation expense for awards granted under the Stock Plan of $28 million and $11 million during the three months ended March 31, 2015 and 2014, respectively, which includes amounts reimbursed by hotel owners. As of March 31, 2015, unrecognized compensation costs for unvested awards was approximately $172 million, which is expected to be recognized over a weighted-average period of 2.1 years on a straight-line basis.
	As of March 31, 2015, there were 68,334,884 shares of common stock available for future issuance under the Stock Plan.
	Restricted Stock Units
	During the three months ended March 31, 2015, we issued 2,017,138 RSUs with a grant date fair value of $27.46, which generally vest in annual installments over two or three years from the date of grant. Vested RSUs generally are settled for our common stock, with the exception of certain awards that are settled in cash.
	Stock Options
	During the three months ended March 31, 2015, we issued 928,585 options with an exercise price of $27.46, which vest over three years from the date of grant, and terminate 10 years from the date of grant or earlier if the individual’s service terminates.
	The grant date fair value of these option grants was $8.39, which was determined using the Black-Scholes-Merton option-pricing model with the following assumptions:
	Expected volatility(1)	28	%
	Dividend yield(2)	—	%
	Risk-free rate(3)	1.67	%
	Expected term (in years)(4)	6
	____________
	(1)	Due to limited trading history for our common stock, we did not have sufficient information available on which to base a reasonable and supportable estimate of the expected volatility of our share price. As a result, we used an average historical volatility of our peer group over a time period consistent with our expected term assumption in addition to our historical volatility. Our peer group was determined based upon companies in our industry with similar business models and is consistent with those used to benchmark our executive compensation.
	(2)	At the date of grant we had no plans to pay dividends during the expected term of these options.
	(3)	Based on the yields of U.S. Department of Treasury instruments with similar expected lives.
	(4)	Estimated using the average of the vesting periods and the contractual term of the options.
	As of March 31, 2015, 304,940 options were exercisable.
	Performance Shares
	During the three months ended March 31, 2015, we issued 1,227,140 performance shares. The performance shares are settled at the end of the three-year performance period with 50 percent of the shares subject to achievement based on a measure of (1) the Company’s total shareholder return relative to the total shareholder returns of members of a peer company group ("relative shareholder return") and the other 50 percent of the shares subject to achievement based on (2) the Company’s earnings before interest expense, taxes and depreciation and amortization ("EBITDA") compound annual growth rate ("EBITDA CAGR").
	The grant date fair value of these performance share grants based on relative shareholder return was $32.98, which was determined using a Monte Carlo simulation valuation model with the following assumptions:
	Expected volatility(1)	24	%
	Dividend yield(2)	—	%
	Risk-free rate(3)	1.04	%
	Expected term (in years)(4)	2.8

	The grant date fair value of these performance share grants based on our EBITDA CAGR was $27.46. For these shares, we determined that the performance condition is probable of achievement and as of March 31, 2015, we recognized compensation expense as follows:
		Achievement Percentage
	Performance shares granted in 2014	150%
	Performance shares granted in 2015	100%
	Promote Plan
	Prior to December 2013, certain members of our senior management team participated in an executive compensation plan (the "Promote Plan"). Equity awards under the Promote Plan were exchanged for restricted shares of common stock in connection with our initial public offering and 80 percent have vested as of December 11, 2014. The remaining 20 percent will vest on the date that our Sponsor ceases to own 50 percent or more of the shares of the Company, contingent on employment through that date, or on the separation date for employees terminated under certain circumstances specified in the Promote Plan agreement.
	During the three months ended March 31, 2015, the vesting conditions of these restricted shares of common stock were modified to accelerate vesting for two participants such that the remaining 20 percent of each participant's award would vest on their respective termination dates, whereas the award would not have otherwise vested. As a result of this modification, we recorded incremental compensation expense of $1 million during the three months ended March 31, 2015.
	During the three months ended March 31, 2015 and 2014, total compensation expense recognized for the Promote Plan was $2 million and $13 million, respectively. As of March 31, 2015, unrecognized compensation expense was $64 million, which is subject to the achievement of a performance condition in the form of a liquidity event that was not probable as of March 31, 2015.

Segment Reporting [Abstract]
Business Segments	Business Segments
	We are a diversified hospitality company with operations organized in three distinct operating segments: ownership, management and franchise and timeshare. Each segment is managed separately because of its distinct economic characteristics.
	The ownership segment includes 131 hotels consisting of 52,133 rooms that we wholly own or lease, as well as consolidated non-wholly owned entities and consolidated VIEs. As of March 31, 2015, this segment included 125 wholly owned and leased hotels, three non-wholly owned hotels and three hotels of consolidated VIEs. While we do not include equity in earnings (losses) from unconsolidated affiliates in our measures of segment revenues, we manage these investments in our ownership segment. Our unconsolidated affiliates are primarily investments in entities that owned or leased 16 hotels and one condominium management company totaling 8,399 rooms as of March 31, 2015.
	The management and franchise segment includes all of the hotels we manage for third-party owners, as well as all franchised hotels operated or managed by someone other than us under one of our proprietary brand names in our brand portfolio. As of March 31, 2015, this segment included 518 managed hotels and 3,652 franchised hotels totaling 4,170 hotels consisting of 653,351 rooms. This segment also earns fees for managing properties in our ownership and timeshare segments.
	The timeshare segment includes the development of vacation ownership clubs and resorts, marketing and selling of timeshare intervals, providing timeshare customer financing and resort operations. This segment also provides assistance to third-party developers in selling their timeshare inventory. As of March 31, 2015, this segment included 44 timeshare properties totaling 6,818 units.
	Corporate and other represents revenues and related operating expenses generated by the incidental support of hotel operations for owned, leased, managed and franchised hotels and other rental income, as well as corporate assets and related expenditures.
	The performance of our operating segments is evaluated primarily based on Adjusted EBITDA. We define Adjusted EBITDA as EBITDA, further adjusted to exclude certain items, including, but not limited to, gains, losses and expenses in connection with: (i) asset dispositions for both consolidated and unconsolidated investments; (ii) foreign currency transactions; (iii) debt restructurings/retirements; (iv) non-cash impairment losses; (v) furniture, fixtures and equipment ("FF&E") replacement reserves required under certain lease agreements; (vi) reorganization costs; (vii) share-based and certain other compensation expenses; (viii) severance, relocation and other expenses; and (ix) other items. To align with management's view of allocating resources and assessing the performance of our segments and to facilitate comparisons with our competitors, beginning in the first quarter of 2015 Adjusted EBITDA excluded all share-based compensation expense, not just share-based compensation recognized in connection with equity issued prior to and in connection with our initial public offering. We have applied this change in the definition to 2014 historical results presented to allow for comparability.
	The following table presents revenues and Adjusted EBITDA for our reportable segments, reconciled to consolidated amounts:

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Commitments and Contingencies
	As of March 31, 2015, we had outstanding guarantees of $25 million, with remaining terms ranging from five years to eight years, for debt and other obligations of third parties. We have one letter of credit for $25 million that has been pledged as collateral for one of these guarantees. Although we believe it is unlikely that material payments will be required under these guarantees or letters of credit, there can be no assurance that this will be the case.
	We have also provided performance guarantees to certain owners of hotels that we operate under management contracts. Most of these guarantees allow us to terminate the contract, rather than fund shortfalls, if specified performance levels are not achieved. However, in limited cases, we are obligated to fund performance shortfalls. As of March 31, 2015, we had seven contracts containing performance guarantees, with expirations ranging from 2018 to 2030, and possible cash outlays totaling approximately $109 million. Our obligations under these guarantees in future periods are dependent on the operating performance levels of these hotels over the remaining terms of the performance guarantees. We do not have any letters of credit pledged as collateral against these guarantees. As of March 31, 2015 and December 31, 2014, we recorded current liabilities of approximately $7 million and $8 million, respectively, and non-current liabilities of approximately $31 million and $37 million, respectively, in our condensed consolidated balance sheets for obligations under our outstanding performance guarantees that are related to certain VIEs for which we are not the primary beneficiary.
	As of March 31, 2015, we had outstanding commitments under third-party contracts of approximately $110 million for capital expenditures at certain owned and leased properties, including our consolidated VIEs. Our contracts contain clauses that allow us to cancel all or some portion of the work. If cancellation of a contract occurred, our commitment would be any costs incurred up to the cancellation date, in addition to any costs associated with the discharge of the contract.
	We have entered into an agreement with an affiliate of the owner of a hotel whereby we have agreed to provide a $60 million junior mezzanine loan to finance the construction of a new hotel. The junior mezzanine loan will be subordinated to a senior mortgage loan and senior mezzanine loan provided by third parties unaffiliated with us and will be funded on a pro rata basis with these loans as the construction costs are incurred. During the three months ended March 31, 2015, we funded $2 million of this commitment, which was included in financing receivables, net in our condensed consolidated balance sheet as of March 31, 2015. We currently expect to fund the remainder of our commitment as follows: $22 million in the remainder of 2015, $34 million in 2016 and $2 million in 2017.
	We have entered into an agreement with a developer in Las Vegas, Nevada, whereby we have agreed to purchase residential units from the developer that we will convert to timeshare units to be marketed and sold under our Hilton Grand Vacations brand. Subject to certain conditions, we are required to purchase approximately $92 million of inventory ratably over a maximum period of four years, which is equivalent to purchases of approximately $6 million per quarter. During the three months ended March 31, 2015 and 2014, we purchased $5 million and $11 million, respectively, of inventory under this agreement. As of March 31, 2015, our contractual obligations pursuant to this agreement for the remainder of 2015 and the year ended December 31, 2016 were $19 million and $4 million, respectively.
	During 2010, an affiliate of our Sponsor settled a $75 million liability on our behalf in conjunction with a lawsuit settlement by entering into service contracts with the plaintiff. We recorded the portion settled by this affiliate as a capital contribution. Additionally, as part of the settlement, we entered into a guarantee with the plaintiff to pay any shortfall that this affiliate does not fund related to those service contracts up to the value of the settlement amount made by the affiliate. The remaining potential exposure under this guarantee as of March 31, 2015 was approximately $30 million. We have not accrued a liability for this guarantee as we believe the likelihood of any material funding to be remote.
	We are involved in other litigation arising from the normal course of business, some of which includes claims for substantial sums. Accruals are recorded when the outcome is probable and can be reasonably estimated in accordance with applicable accounting requirements regarding accounting for contingencies. While the ultimate results of claims and litigation cannot be predicted with certainty, we expect that the ultimate resolution of all pending or threatened claims and litigation as of March 31, 2015 will not have a material effect on our condensed consolidated results of operations, financial position or cash flows.

Condensed Consolidating Guarantor Financial Information [Abstract]
Condensed Consolidating Guarantor Financial Information	Condensed Consolidating Guarantor Financial Information
	In October 2013, Hilton Worldwide Finance LLC and Hilton Worldwide Finance Corp. (the "Subsidiary Issuers"), entities formed in August 2013 which are 100 percent owned by the Parent, issued the $1.5 billion of 5.625% senior notes due in 2021 (the "Senior Notes"). The obligations of the Subsidiary Issuers are guaranteed jointly and severally on a senior unsecured basis by the Parent, and certain of the Parent's 100 percent owned domestic restricted subsidiaries (the "Guarantors"). The indenture that governs the Senior Notes provides that any subsidiary of the Company that provides a guarantee of a senior secured credit facility consisting of the Revolving Credit Facility and the Term Loans (the "Senior Secured Credit Facility") will guarantee the Senior Notes. None of our foreign subsidiaries or U.S. subsidiaries owned by foreign subsidiaries or conducting foreign operations; our non-wholly owned subsidiaries; our subsidiaries that secure the CMBS Loan and $514 million in mortgage loans; or certain of our special purpose subsidiaries formed in connection with our Timeshare Facility and Securitized Timeshare Debt guarantee the Senior Notes (collectively, the "Non-Guarantors").
	The guarantees are full and unconditional, subject to certain customary release provisions. The indenture that governs the Senior Notes provides that any Guarantor may be released from its guarantee so long as: (a) the subsidiary is sold or sells all of its assets; (b) the subsidiary is released from its guaranty under the Senior Secured Credit Facility; (c) the subsidiary is declared "unrestricted" for covenant purposes; or (d) the requirements for legal defeasance or covenant defeasance or to discharge the indenture have been satisfied.
	The following schedules present the condensed consolidating financial information as of March 31, 2015 and December 31, 2014, and for the three months ended March 31, 2015 and 2014, for the Parent, Subsidiary Issuers, Guarantors and Non-Guarantors.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events
	In April 2015, in connection with our tax deferred exchange of real property, we executed an agreement to purchase an additional property for $112 million and paid a $10 million earnest money deposit.
	In April 2015, we entered into an agreement to sell the Hilton Sydney for A$442 million Australian Dollars, which is payable in cash at closing and is subject to customary pro rations and adjustments. At closing, we will enter into a management agreement with a 50-year term, including extensions solely at our option, with the buyer. The buyer has provided a cash deposit of A$44 million Australian Dollars, which is being held in escrow as earnest money, and the completion of the transaction is subject to customary closing conditions. Subject to specified terms and conditions, the closing is expected to occur by June 30, 2015. We intend to use the net proceeds to further reduce the amount outstanding on our Term Loan.
	In April 2015, we made a voluntary prepayment of $100 million on our Term Loans.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
ASU 2015-02 Consolidation	In February 2015, the FASB issued ASU No. 2015-02 ("ASU 2015-02"), Consolidation (Topic 810) - Amendments to the Consolidation Analysis. This ASU modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The provisions of ASU 2015-02 are effective for reporting periods beginning after December 15, 2015; early adoption is permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.
ASU 2015-01 Extraordinary and Unusual Items	In January 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-01 ("ASU 2015-01"), Income Statement-Extraordinary and Unusual Items (Subtopic 225-20). This ASU eliminates the concept of extraordinary items and the related income statement presentation of such items. The provisions of ASU 2015-01 are effective for reporting periods beginning after December 15, 2015. We elected, as permitted by the standard, to early adopt ASU 2015-01 on a prospective basis as of January 1, 2015. The adoption did not have an effect on our condensed consolidated financial statements.
ASU 2015-03 Presentation of Debt Issuance Costs	In April 2015, the FASB issued ASU No. 2015-03 ("ASU 2015-03"), Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset, which is consistent with the presentation of debt discounts or premiums. The provisions of ASU 2015-03 are effective for reporting periods beginning after December 31, 2015; early adoption is permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.
ASU 2014-15 Going Concern	In August 2014, the FASB issued ASU No. 2014-15 ("ASU 2014-15"), Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This ASU requires management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements issue date. The provisions of ASU 2014-15 are effective for reporting periods beginning after December 15, 2016; early adoption is permitted. The adoption of this ASU is not expected to have a material effect on our consolidated financial statements.
ASU 2014-09 Revenue Recognition Policy	In May 2014, the FASB issued ASU No. 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers (Topic 606). This ASU supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)," and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The provisions of ASU 2014-09 are effective for reporting periods beginning after December 15, 2016 and are to be applied retrospectively; early adoption is not permitted. We are currently evaluating the effect that this ASU will have on our consolidated financial statements.

As a result, we used an average historical volatility of our peer group over a time period consistent with our expected term assumption in addition to our historical volatility. Our peer group was determined based upon companies in our industry with similar business models and is consistent with those used to benchmark our executive compensation.
	(2)	At the date of grant we had no plans to pay dividends during the expected term of these performance shares.
	(3)	Based on the yields of U.S. Department of Treasury instruments with similar expected lives.
