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, Encore, an expansion at 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 the Company's U.S. online sports betting and gaming business, social casino business, and Wynn Resorts' strategic partner, BetBull Limited ("BetBull"). Wynn Resorts holds an approximately 74% interest in, and consolidates, Wynn Interactive. The results of Wynn Interactive's operations are presented within Corporate and other in the accompanying condensed consolidated financial statements, except where otherwise noted. Recent Developments Related to COVID-19 Since the outbreak of COVID-19 in early 2020, 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. As part of the immediate response to the initial outbreak of COVID-19, each of the Company's properties was subject to partial or full closure for varying lengths of time during 2020, and have all since reopened. Several vaccines have been granted authorization in numerous countries and are being rolled out to citizens based on availability and priority of need. There can be no assurance as to when a sufficient number of individuals will be vaccinated, permitting travel restrictions to be fully lifted. Macau Operations Visitation to Macau has fallen significantly since the outbreak of COVID-19, driven by the strong deterrent effect of the COVID-19 pandemic on travel and social activities, quarantine measures in Macau and elsewhere, travel and entry restrictions and conditions in Macau, the PRC, Hong Kong and Taiwan involving COVID-19 testing, among other things, and the suspension or reduced accessibility of transportation to and from Macau. Beginning in June 2020 certain restrictions and conditions have eased to allow for visitation to Macau as certain regions recover from the COVID-19 pandemic. Quarantine-free travel, subject to COVID-19 safeguards such as testing and the usual visa requirements, has been reintroduced between Macau and most areas and cities within the PRC, and in September 2020, PRC authorities fully resumed the IVS exit visa program, which permits individual PRC citizens from nearly 50 PRC cities to travel to Macau for tourism purposes. On August 3, 2021, in response to a risk of a community outbreak, the government of Macau has announced enhanced measures including tighter border control and strict mandatory COVID-19 testing requirements. Las Vegas Operations and Encore Boston Harbor The Company’s Las Vegas Operations and Encore Boston Harbor had each implemented certain COVID-19 specific protective measures, 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. On April 8, 2021, Encore at Wynn Las Vegas resumed full operations. On May 3, 2021, the Company's Las Vegas Operations were permitted by the Nevada Gaming Control Board to reopen all gaming areas to 100% of capacity, with no continuing table game or slot machine spacing restrictions. On July 27, 2021, the Governor of Nevada issued an emergency directive, in accordance with new recommendations from the Centers for Disease Control, re-imposing mask protection requirements in all public indoor areas effective July 30, 2021. At Encore Boston Harbor, on January 25, 2021, limitations on operating hours that had been in place since November 2020 were lifted, and the property restored certain operations and reopened its hotel tower on a Thursday through Sunday schedule. On April 27, 2021, the Governor of Massachusetts announced a phased plan for further reopening and on May 28, 2021 signed an executive order rescinding the COVID-19 related restrictions and limitations on businesses as of May 29, 2021. The property continues to operate its hotel tower Thursday through Sunday. Summary The COVID-19 pandemic has had and will continue to have an adverse effect on the Company's results of operations. Notwithstanding the easing of certain COVID-19 protective measures by authorities throughout the world, certain travel restrictions, quarantine measures, testing requirements, and capacity limitations remain in effect at our Macau Operations, and the Company is currently unable to determine when protective measures and the suspension of certain offerings in effect at our Macau Operations 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 June 30, 2021, the Company had total cash and cash equivalents, excluding restricted cash, of $2.80 billion, and had access to $834.2 million of available borrowing capacity from the WRF Revolving Facility and $293.2 million of available borrowing capacity from the Wynn Macau Revolving Facility. The Company has suspended its dividend program. Given the Company's liquidity position at June 30, 2021, the Company believes it is able to support continuing operations and respond to the current COVID-19 pandemic challenges. Macau Gaming Concession The term of the Company's concession agreement with the Macau government ends on June 26, 2022. If the term of this concession agreement is not extended or renewed or is not replaced by a new gaming concession, all of the Company's gaming operations and related equipment in Macau will be automatically transferred to the Macau government without compensation on that date and the Company will cease to generate gaming revenues from its Macau Operations. In addition, under the indentures governing the Company's $4.7 billion aggregate principal amount of WML Senior Notes, upon the occurrence of any event after which none of WML or any of its subsidiaries own or manage casino or gaming areas or operate casino games of fortune and chance in Macau in substantially the same manner as they are owning or managing casino or gaming areas or operating casino games as of the issue date of the respective senior notes, for a period of 10 consecutive days or more, and such event has a material adverse effect on the financial condition, business, properties or results of operations of WML and its subsidiaries, taken as a whole, holders of the WML Senior Notes can require the Company to repurchase all or any part of the WML Senior Notes at par, plus any accrued and unpaid interest (the "Special Put Option"). The Macau government has publicly commented that it is studying the process by which concessions and subconcessions may be renewed, extended or issued. The Company is monitoring developments with respect to the Macau government's concession renewal or extension process, and at this time believes that its concession will be renewed or extended beyond June 26, 2022. The failure to extend or renew the Company's concession or obtain a new concession and the resulting ability of the WML Senior Note holders to exercise the Special Put Option would have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows. Business Combination Agreement On May 10, 2021, Wynn Interactive entered into a business combination agreement (the "Business Combination Agreement") with Austerlitz Acquisition Corporation I, a Cayman Islands exempted company ("Austerlitz I"), and Wave Merger Sub Limited, an exempted company limited by shares incorporated in Bermuda and a direct, wholly owned subsidiary of Austerlitz I ("Merger Sub"). The Business Combination Agreement provides for, among other things, the consummation of the following transactions: (i) Austerlitz I will transfer by way of continuation from the Cayman Islands to Bermuda and change its name to "Wynn Interactive, Limited"; and (ii) Merger Sub will merge with and into Wynn Interactive (the "Merger"), with Wynn Interactive being the surviving company of the Merger and direct, wholly owned subsidiary of Austerlitz I. Upon closing of the transaction, assuming no share redemptions by the public stockholders of Austerlitz I, the Company is expected to retain an approximately 58% equity interest (and approximately 72% voting interest) in Wynn Interactive. The proposed business combination is expected to close by the end of 2021, subject to approval by Austerlitz I's stockholders, gaming regulatory approval and other customary closing conditions.
