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. 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, the Company's casino operations at Wynn Palace and Wynn Macau reopened on a reduced basis and have since been fully restored; however, certain health safeguards, such as traveler quarantines, limiting the number of seats per table game, slot machine spacing, temperature checks, mask protection, and health declarations remain in effect at the present time. The Company is currently unable to determine when these measures will be lifted. Visitation to Macau has fallen meaningfully since the outbreak of COVID-19, driven by the outbreak'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, quarantine measures, travel and entry restrictions in Macau, Hong Kong and certain cities and regions in mainland China, the suspension of ferry services and other modes of transportation with Macau and regionally, and the ban on entry or enhanced quarantine requirements for any residents of Greater China attempting to enter Macau. Persons who are not residents of Greater China are barred from entry to Macau at this time. On March 14, 2020, the Massachusetts Gaming Commission temporarily suspended operations at all casinos in Massachusetts, including Encore Boston Harbor. On March 17, 2020, the Nevada government suspended all casino and non-essential operations, including all operations at Wynn Las Vegas. Accordingly, Encore Boston Harbor and Wynn Las Vegas ceased all operations and closed to the public on March 15, 2020 and March 17, 2020, respectively. Both resorts will remain closed until authorized to re-open under U.S. and state government directives. During the first quarter of 2020, the Company committed to pay salary, tips and benefits continuation for all U.S. employees, inclusive of part-time employees, through May 15, 2020. The Company has accrued $75.7 million of expense related to this commitment for the period from April 1 through May 15, 2020 within the accompanying Condensed Consolidated Financial Statements. In May 2020, the Company announced that it had extended its commitment through May 31, 2020. The COVID-19 outbreak has had and will continue to have an adverse effect on the Company's results of operations. 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 March 31, 2020, the Company had total cash and cash equivalents, excluding restricted cash, of $2.88 billion, and had access to $40.9 million and $74.2 million of available borrowing capacity from the WRF Revolving Facility and Wynn Macau Revolving Facility, respectively. In addition, the Company has suspended its quarterly dividend program and has postponed major project capital expenditures. Given the Company's liquidity position at March 31, 2020 and the steps the Company has taken subsequent to March 31, 2020 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.
