Organization and Basis of Presentation	'
	ORGANIZATION AND BASIS OF PRESENTATION
	Organization
	Marina District Development Company, LLC, a New Jersey limited liability company ("MDDC"), is the parent of Marina District Finance Company, Inc., a New Jersey corporation ("MDFC"). MDFC is a 100% owned finance subsidiary of MDDC, which has fully and unconditionally guaranteed MDFC's securities.
	MDDC was incorporated in July 1998 and has been operating since July 3, 2003. MDFC was incorporated in 2000 and has been a wholly owned subsidiary of MDDC since its inception. We developed, own and operate Borgata Hotel Casino and Spa, including The Water Club at Borgata (collectively, "Borgata"). Borgata is located on a 45.6-acre site at Renaissance Pointe in Atlantic City, New Jersey. Borgata is an upscale destination resort and gaming entertainment property.
	Borgata was developed as a joint venture between Boyd Atlantic City, Inc. ("BAC"), a wholly owned subsidiary of Boyd Gaming Corporation ("Boyd"), and MAC, Corp. ("MAC"), a second tier, wholly owned subsidiary of MGM Resorts International (the successor-in-interest to MGM MIRAGE) ("MGM"). The joint venture operates pursuant to an operating agreement between BAC and MAC (the "Operating Agreement"), in which BAC and MAC each originally held a 50% interest in Marina District Development Holding Co., LLC, MDDC's parent holding company ("MDDHC").
	As managing member of MDDHC pursuant to the terms of the Operating Agreement, BAC, through MDDHC, has responsibility for the oversight and management of our day-to-day operations. We do not presently record a management fee to BAC, as our management team performs these services directly or negotiates contracts to provide for these services. As a result, the costs of these services are directly borne by us and are reflected in our consolidated financial statements. Boyd, the parent of BAC, is a diversified operator of 21 wholly owned gaming entertainment properties. Headquartered in Las Vegas, Nevada, Boyd has other gaming operations in Nevada, Illinois, Indiana, Iowa, Kansas, Louisiana and Mississippi.
	On March 24, 2010, MAC transferred its 50% ownership interest (the "MGM Interest") in MDDHC, and certain land leased to MDDC, into a divestiture trust, of which MGM and its subsidiaries are the economic beneficiaries (the "Divestiture Trust"), for sale to a third-party in connection with MGM's settlement agreement with the New Jersey Division of Gaming Enforcement ("NJDGE"). MGM has subsequently announced that it had entered into an amended settlement agreement with the NJDGE, as approved by the New Jersey Casino Control Commission ("NJCCC"). The amended agreement provided that until March 24, 2013, MGM had the right to direct the Divestiture Trust to sell the MGM Interest. If a sale was not concluded by that time, the Divestiture Trust was to be responsible for selling MGM's Interest during the following 12-month period, or not later than March 24, 2014. Subsequent to a Joint Petition of MGM, Boyd and MDDC, the NJCCC, on February 13, 2013, approved amendments to the Stipulation of Settlement and Trust Agreement which permits MGM to file an application for a statement of compliance, which, if approved, could permit MGM to reacquire its interest in MDDC. The deadline requiring MGM and the Divestiture Trust to sell the MGM Interest has been tolled to allow the NJCCC to complete a review of the application. BAC has a right of first refusal on any sale of the MGM Interest. We continue to operate under normal business conditions throughout MGM's sales efforts, and do not believe that it has had or will have a material impact on our operations.
	Upon the transfer of the MGM Interest into the Divestiture Trust, MGM relinquished all of its specific participating rights under the Operating Agreement, and Boyd effectively obtained control of Borgata. As a result, beginning on March 24, 2010, our financial position and results of operations have been included in the consolidated financial statements of Boyd. This resulting change in control required acquisition method accounting by Boyd in accordance with the authoritative accounting guidance for business combinations; however, there was no resulting direct impact on our consolidated financial statements. Accordingly, our financial position and results of operations as reported herein will differ from the results as consolidated with and separately reported by Boyd, as certain fair value and other acquisition method accounting adjustments have not been pushed down to our stand-alone consolidated financial statements.
	Basis of Presentation
	Interim Condensed Consolidated Financial Statements
	The accompanying unaudited condensed consolidated financial statements of MDDC have been prepared in accordance with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and footnote disclosures necessary for complete financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP").
	The results for the periods indicated are unaudited, but reflect all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of financial position, results of operations and cash flows. Results of operations and cash flows for the interim periods presented herein are not necessarily indicative of the results that would be achieved during a full year of operations or in future periods.
	These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the U.S. Securities and Exchange Commission ("SEC") on March 28, 2014.
	Principles of Consolidation
	The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP and include the accounts of MDDC and MDFC.
	All intercompany accounts and transactions have been eliminated.

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Restricted Cash
	Restricted cash consists primarily of advance payments related to amounts restricted by regulation for gaming purposes. These restricted cash balances are invested in highly liquid instruments with a maturity of 90 days or less.
	CRDA Investments
	Pursuant to the New Jersey Casino Control Act ("Casino Control Act"), as a casino licensee, we are assessed an amount equal to 1.25% of our land-based gross gaming revenues in order to fund qualified investments. This assessment is made in lieu of an investment alternative tax equal to 2.5% of land-based gross gaming revenues. The Casino Control Act also provides for an assessment of licensees equal to 2.5% of online gross gaming revenues, which is made in lieu of an investment alternative tax equal to 5.0% of online gross gaming revenues. Once our funds are deposited with the New Jersey Casino Reinvestment Development Authority ("CRDA"), qualified investments may be satisfied by: (i) the purchase of bonds issued by the CRDA at below market rates of interest; (ii) direct investment in CRDA-approved projects; or (iii) a donation of funds to projects as determined by the CRDA. According to the Casino Control Act, funds on deposit with the CRDA are invested by the CRDA and the resulting income is shared two-thirds to the casino licensee and one-third to the CRDA. Further, the Casino Control Act requires that CRDA bonds be issued at statutory rates established at two-thirds of market value.
	We are required to make quarterly deposits with the CRDA to satisfy our investment obligations. At the date the obligation arises, we record charges to expense (i) pursuant to the respective underlying agreements for obligations with identified qualified investments and (ii) by applying a one-third valuation reserve to our obligations that are available to fund qualified investments to reflect the anticipated below market return on investment. The one-third valuation reserve is adjusted accordingly, if necessary, when a qualified investment is identified. Our deposits with the CRDA, net of valuation reserves held by us, were $6.7 million and $4.6 million as of June 30, 2014 and December 31, 2013, respectively, and are included in other assets, net, on our condensed consolidated balance sheets.
	Promotional Allowances
	The retail value of accommodations, food and beverage, and other services furnished to guests on a complimentary basis is included in gross revenues and then deducted as promotional allowances. Promotional allowances also include incentives such as cash, goods and services (such as complimentary rooms and food and beverages) earned in our loyalty programs. We reward customers, through the use of loyalty programs, with points based on amounts wagered that can be redeemed for a specified period of time, principally for restricted free play slot machine credits and complimentary goods and services. We record the estimated retail value of these goods and services as revenue and then record a corresponding deduction as promotional allowances.
	The amounts included in promotional allowances are as follows:
		Three Months Ended						Six Months Ended
		June 30,						June 30,
	(In thousands)	2014			2013			2014		2013
	Rooms	$	17,667		$	17,308		$	34,335	$	34,393

	Other	28,965			21,323			51,761		41,663
	Total promotional allowances	$	58,719		$	50,953		$	110,335	$	100,789
	The estimated costs of providing such promotional allowances are as follows:
		Three Months Ended						Six Months Ended
		June 30,						June 30,
	(In thousands)	2014			2013			2014		2013
	Rooms	$	5,485		$	5,351		$	10,699	$	10,720

	Other	2,814			2,609			5,180		4,925
	Total cost of promotional allowances	$	17,898		$	17,324		$	35,150	$	34,580
	Gaming Taxes
	In New Jersey, we are subject to an annual tax assessment based on gross gaming revenues of 8% on our land-based gross gaming revenues and 15% on our online gross gaming revenues. These gaming taxes are recorded as a gaming expense in the condensed consolidated statements of operations. These taxes were $12.8 million and $11.0 million during the three months ended June 30, 2014 and 2013, respectively, and $24.9 million and $21.8 million during the six months ended June 30, 2014 and 2013, respectively.
	Income Taxes
	As a single member LLC, MDDC is treated as a disregarded entity for federal income tax purposes. As such, it is not subject to federal income tax and its income is treated as earned by its member, MDDHC. MDDHC is treated as a partnership for federal income tax purposes and federal income taxes are the responsibility of its members. In New Jersey, casino partnerships are subject to state income taxes under the Casino Control Act; therefore, MDDC, considered a casino partnership, is required to record New Jersey state income taxes. In 2004, MDDC was granted permission by the state of New Jersey, pursuant to a ruling request, to file a consolidated New Jersey corporation business tax return with the members of its parent, MDDHC. The amounts reflected in the condensed consolidated financial statements are reported as if MDDC was taxed for state purposes on a stand-alone basis; however, MDDC files a consolidated state tax return with the members of MDDHC.
	The amounts due to these members are a result of each member's respective tax attributes included in the consolidated state tax return. A reconciliation of the components of our stand-alone state income taxes receivable is presented below:
		June 30,			December 31,
	(In thousands)	2014			2013
	Amounts payable to members of MDDHC	$	—		$	—
	Amounts receivable - State	(9		)	(1,037		)
	Income taxes payable (receivable), net	$	(9	)	$	(1,037	)
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
	Recently Issued Accounting Pronouncements
	A variety of proposed or otherwise potential accounting standards are currently under study by standard-setting organizations and certain regulatory agencies. Because of the tentative and preliminary nature of such proposed standards, we have not yet determined the effect, if any, that the implementation of such proposed standards would have on our consolidated financial statements.
	Accounting Standards Update 2014-09 Revenue from Contracts with Customers (Topic 606) ("Update 2014-09")
	In May 2014, the FASB issued ASU 2014-09. Update 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is not permitted. The impact of the adoption of Update 2014-09 to the Company's consolidated financial position or results of operations is currently under evaluation.

	Commitments
	There have been no material changes to our commitments described under Note 6, Commitments and Contingencies, in our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on March 28, 2014.
	Contingencies
	Borgata Property Taxes
	We have filed tax appeal complaints, in connection with our property tax assessments for tax years 2009 through 2014, in New Jersey Tax Court ("Tax Court"). The trial for tax years 2009 and 2010 was held during the second quarter of 2013 and a decision was issued on October 18, 2013. The assessor valued our real property at approximately $2.3 billion. The Tax Court found in our favor and reduced our real property valuation to $880 million and $870 million for tax years 2009 and 2010, respectively. The City of Atlantic City (the "City") filed an appeal in the New Jersey Superior Court - Appellate Division ("Appellate Court") in November 2013. No trial date has been set for the Appellate Court hearing. We have paid our property tax obligations consistent with the assessor’s valuation and based on the Tax Court’s decision, we estimate the 2009 and 2010 property tax refunds and related statutory interest will be approximately $48.0 million and $9.0 million, respectively. We can provide no assurances that the Tax Court’s decision in the 2009-2010 appeal will be upheld at the appellate level. Due to the uncertainty surrounding the ultimate resolution of the City’s appeal, we will not recognize any gain until a final, non-appealable decision has been rendered.
	On June 5, 2014, we entered into a settlement agreement with the City. The agreement resolved the tax appeal complaints we filed in connection with property tax assessments for tax years 2011 through 2014. Under the terms of the agreement, we are entitled to receive a tax refund of $88.25 million for tax years 2011 through 2013, as well as an estimated tax credit of $17.85 million for tax year 2014. Additionally, the City has agreed to a defined property tax valuation for tax year 2015. Although the tax rate for 2015 is unknown, we believe that the revised valuation will result in significantly lower real estate taxes as compared to 2013. In exchange, we have agreed to relinquish our right to further contest the property tax assessments for tax years 2011 through 2015, contingent upon the City fulfilling its obligations under the agreement. The agreement does not affect the pending appeals of the property tax assessments for tax years 2009 and 2010. Per the terms of the agreement, the City intends to fulfill its obligation to pay the refund to us through a bond issuance; however, such bond issuance is subject to additional state and local agency approvals and general market conditions at the time of the proposed issuance. In the event that the City does not issue bonds, or otherwise fails to pay the refund, we retain our right to compel a trial on the filed appeals. We cannot be certain that the City will issue bonds or fund their obligations under the agreement through other sources. Due to this uncertainty, we will not record the recovery of the $88.25 million in previously paid property taxes until the City has successfully issued bonds or obtained other dedicated sources of funding in an amount sufficient to pay the refund for tax years 2011-2013 per the terms of the agreement.
	Legal Matters
	We are subject to various claims and litigation in the ordinary course of business. In our opinion, all pending legal matters are either adequately covered by insurance, or, if not insured, will not have a material adverse impact on our financial position, results of operations or cash flows.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	FAIR VALUE MEASUREMENTS
	We have adopted the authoritative accounting guidance for fair value measurements, which does not determine or affect the circumstances under which fair value measurements are used, but defines fair value, expands disclosure requirements around fair value and specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions
	These inputs create the following fair value hierarchy:
	•	Level 1: Quoted prices for identical instruments in active markets.
	•	Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
	•	Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	As required by the guidance for fair value measurements, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Thus, assets and liabilities categorized as Level 3 may be measured at fair value using inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Management's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels.
	Balances Measured at Fair Value
	The fair value of our cash and cash equivalents was $32.8 million and $37.5 million as of June 30, 2014 and December 31, 2013, respectively. The fair value of our restricted cash was $4.8 million as of June 30, 2014. The fair value of our cash and cash equivalents and restricted cash, classified in the fair value hierarchy as Level 1, is based on statements received from our banks at June 30, 2014 and December 31, 2013. The fair value of our CRDA deposits was $6.7 million and $4.6 million as of June 30, 2014 and December 31, 2013, respectively. The fair value of our CRDA deposits, classified in the fair value hierarchy as Level 3, is based on estimates of the realizable value applied to the balances on statements received from the CRDA at June 30, 2014 and December 31, 2013.
	The following table summarizes the fair value of the Company's Level 3 assets:

	Total long-term debt	$	813,400		$	801,260		$	847,272
	The estimated fair value of our Credit Facility at June 30, 2014 and December 31, 2013 approximates its carrying value due to the short-term nature and variable repricing of the underlying Eurodollar loans comprising our Credit Facility. The estimated fair value of our incremental term loan is based on a relative value analysis performed on or about June 30, 2014 and December 31, 2013. The estimated fair value of our senior secured notes is based on quoted market prices as of June 30, 2014 and December 31, 2013.
	There were no transfers between Level 1, Level 2 or Level 3 measurements during the six months ended June 30, 2014.

Accounting Policies [Abstract]	'
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Restricted Cash
	Restricted cash consists primarily of advance payments related to amounts restricted by regulation for gaming purposes. These restricted cash balances are invested in highly liquid instruments with a maturity of 90 days or less.
CRDA Investments [Policy Text Block]	'
	CRDA Investments
	Pursuant to the New Jersey Casino Control Act ("Casino Control Act"), as a casino licensee, we are assessed an amount equal to 1.25% of our land-based gross gaming revenues in order to fund qualified investments. This assessment is made in lieu of an investment alternative tax equal to 2.5% of land-based gross gaming revenues. The Casino Control Act also provides for an assessment of licensees equal to 2.5% of online gross gaming revenues, which is made in lieu of an investment alternative tax equal to 5.0% of online gross gaming revenues. Once our funds are deposited with the New Jersey Casino Reinvestment Development Authority ("CRDA"), qualified investments may be satisfied by: (i) the purchase of bonds issued by the CRDA at below market rates of interest; (ii) direct investment in CRDA-approved projects; or (iii) a donation of funds to projects as determined by the CRDA. According to the Casino Control Act, funds on deposit with the CRDA are invested by the CRDA and the resulting income is shared two-thirds to the casino licensee and one-third to the CRDA. Further, the Casino Control Act requires that CRDA bonds be issued at statutory rates established at two-thirds of market value.
	We are required to make quarterly deposits with the CRDA to satisfy our investment obligations. At the date the obligation arises, we record charges to expense (i) pursuant to the respective underlying agreements for obligations with identified qualified investments and (ii) by applying a one-third valuation reserve to our obligations that are available to fund qualified investments to reflect the anticipated below market return on investment. The one-third valuation reserve is adjusted accordingly, if necessary, when a qualified investment is identified. Our deposits with the CRDA, net of valuation reserves held by us, were $6.7 million and $4.6 million as of June 30, 2014 and December 31, 2013, respectively, and are included in other assets, net, on our condensed consolidated balance sheets.
Revenue Recognition, Allowances [Policy Text Block]	'
	Promotional Allowances
	The retail value of accommodations, food and beverage, and other services furnished to guests on a complimentary basis is included in gross revenues and then deducted as promotional allowances. Promotional allowances also include incentives such as cash, goods and services (such as complimentary rooms and food and beverages) earned in our loyalty programs. We reward customers, through the use of loyalty programs, with points based on amounts wagered that can be redeemed for a specified period of time, principally for restricted free play slot machine credits and complimentary goods and services. We record the estimated retail value of these goods and services as revenue and then record a corresponding deduction as promotional allowances.
Gaming Taxes, Policy [Policy Text Block]	'
	Gaming Taxes
	In New Jersey, we are subject to an annual tax assessment based on gross gaming revenues of 8% on our land-based gross gaming revenues and 15% on our online gross gaming revenues. These gaming taxes are recorded as a gaming expense in the condensed consolidated statements of operations. These taxes were $12.8 million and $11.0 million during the three months ended June 30, 2014 and 2013, respectively, and $24.9 million and $21.8 million during the six months ended June 30, 2014 and 2013, respectively.
Income Taxes, Policy [Policy Text Block]	'
	Income Taxes
	As a single member LLC, MDDC is treated as a disregarded entity for federal income tax purposes. As such, it is not subject to federal income tax and its income is treated as earned by its member, MDDHC. MDDHC is treated as a partnership for federal income tax purposes and federal income taxes are the responsibility of its members. In New Jersey, casino partnerships are subject to state income taxes under the Casino Control Act; therefore, MDDC, considered a casino partnership, is required to record New Jersey state income taxes. In 2004, MDDC was granted permission by the state of New Jersey, pursuant to a ruling request, to file a consolidated New Jersey corporation business tax return with the members of its parent, MDDHC. The amounts reflected in the condensed consolidated financial statements are reported as if MDDC was taxed for state purposes on a stand-alone basis; however, MDDC files a consolidated state tax return with the members of MDDHC.
	The amounts due to these members are a result of each member's respective tax attributes included in the consolidated state tax return. A reconciliation of the components of our stand-alone state income taxes receivable is presented below:

	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
