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. 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, 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 Chinese government's suspension of its visa and group tour schemes that allow mainland Chinese residents to travel to Macau, various quarantine measures in Macau and elsewhere, travel and entry restrictions in Macau, Hong Kong, Taiwan, and 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. 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 are being eased as the region gradually recovers 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. Quarantine requirements for those traveling between Hong Kong and Macau have been announced to remain effective until at least September 7, 2020, at which time they may be lifted. In the initial phase of opening travel channels between Macau and other regions, it is expected that all visitors seeking entry to Macau will need to test negative for COVID-19 before entering Macau. Although Mainland China and Macau have recently announced several policies or changes to policies which relax certain visa issuance, border control and quarantine requirements, stringent health declarations, testing and other procedures remain in place and the Individual Visitor Scheme 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, has yet to restart. 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. Encore Boston Harbor closed on March 15, 2020, for the remainder of the first and second quarters of 2020. On July 12, 2020, Encore Boston Harbor reopened 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 have been limited to 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. 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 June 30, 2020, the Company had total cash and cash equivalents, excluding restricted cash, of $3.80 billion, and had access to $15.9 million and $24.1 million of available borrowing capacity from the WRF Revolving Facility and Wynn Macau Revolving Facility, respectively. In addition, the Company has suspended its dividend program and has postponed major project capital expenditures. Given the Company's liquidity position at June 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.
