Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization and Business 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. In October 2020, Wynn Interactive Ltd. ("Wynn Interactive") was formed through the merger (the "BetBull Acquisition") of Wynn Resorts' digital gaming businesses and Wynn Resorts' strategic partner, BetBull Limited ("BetBull"). The merger was effected through a series of transactions which resulted in the Company contributing to BetBull its interests in WSI US, LLC and Wynn Social Gaming, LLC, which operate Wynn Resorts' existing U.S. online sports betting and gaming business and social casino business, respectively. Following the merger, Wynn Resorts holds an approximately 72% controlling interest in Wynn Interactive. The results of its operations are presented within Corporate and other in the accompanying consolidated financial statements, except where otherwise noted. For more information on the Betbull Acquisition, see Note 19, "Business Combination." Macau Operations Wynn Palace, which opened in August 2016, features a luxury hotel tower with 1,706 guest rooms, suites and villas, approximately 424,000 square feet of casino space, 14 food and beverage outlets, approximately 37,000 square feet of meeting and convention space, approximately 107,000 square feet of retail space, public attractions including a performance lake and floral art displays, and recreation and leisure facilities. Wynn Macau features two luxury hotel towers with a total of 1,010 guest rooms and suites, approximately 252,000 square feet of casino space, 12 food and beverage outlets, approximately 31,000 square feet of meeting and convention space, approximately 59,000 square feet of retail space, a rotunda show and recreation and leisure facilities. Las Vegas Operations Wynn Las Vegas features two luxury hotel towers with a total of 4,748 guest rooms, suites and villas, approximately 194,000 square feet of casino space, 31 food and beverage outlets, approximately 513,000 square feet of meeting and convention space, approximately 152,000 square feet of retail space (the majority of which is owned and operated under a joint venture of which the Company owns 50.1%), as well as two theaters, three nightclubs and a beach club and recreation and leisure facilities. Encore Boston Harbor On June 23, 2019, the Company opened Encore Boston Harbor, an integrated resort in Everett, Massachusetts, adjacent to Boston along the Mystic River. The property features a luxury hotel tower with a total of 671 guest rooms and suites, approximately 208,000 square feet of casino space, 16 food and beverage outlets, approximately 71,000 square feet of meeting and convention space, and approximately 8,000 square feet of retail space. Public attractions include a waterfront park, floral displays, and water shuttle service to downtown Boston. Recent Developments Related to COVID-19 In January 2020, 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. Several vaccines have been granted authorizations in numerous countries and vaccines are being rolled out to citizens based on their priority of need. There can be no assurance as to when a sufficient number of individuals will be vaccinated, permitting travel restrictions to be lifted. Macau Operations In response to the COVID-19 pandemic, casino operations in Macau were closed for a 15-day period in February 2020 and resumed on a reduced basis on February 20, 2020. On March 20, 2020 casino operations were fully restored; however, certain COVID-19 specific protective measures, such as limiting the number of seats per table game, increasing the spacing between active slot machines and visitor entry checks and requirements involving temperature checkpoints, mask wearing, health declarations and proof of negative COVID-19 test results remain in effect at the present time. 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, the suspension or reduced availability of the Individual Visit Scheme (the “IVS”), group tour scheme and other travel visas for visitors, 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. At present, bans on entry or enhanced quarantine requirements remain in place for people attempting to enter Macau, depending on various conditions such as the usual visa requirements, their COVID-19 test results, purpose of visit, recent travel history and/or other conditions as applicable. While many aspects of these travel restrictions and conditions continue to adversely impact visitations to 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, was reintroduced between Macau and an increasing number of areas and cities within the PRC in progressive phases from June to August 2020, commencing with an area in Guangdong Province, which is adjacent to Macau, and expanding to additional areas and major cities within Guangdong Province, followed by most other areas of the PRC. On September 23, 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. Notwithstanding these developments, certain border control, travel-related restrictions and conditions, including certain quarantine and medical observation measures, stringent health declarations, COVID-19 testing and other procedures remain in place, and all visitors need to test negative for COVID-19 before entering Macau. Given the evolving conditions created by and in response to the COVID-19 pandemic, the Company is currently unable to determine when travel-related restrictions and conditions will be further lifted. Measures that have been lifted or are expected to be lifted may be reintroduced if there are adverse developments in the COVID-19 situation in Macau and other regions with access to Macau. 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. Beginning October 19, 2020, Encore at Wynn Las Vegas adjusted its operating schedule to five days/four nights each week due to currently reduced customer demand levels. Encore Boston Harbor ceased all operations and closed to the public on March 15, 2020, and reopened on July 10, 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, capacity restrictions, and mask protection. Subsequent to reopening, certain food and beverage outlets have remained temporarily closed and our hotel operations were limited to Thursday through Sunday. On November 6, 2020, pursuant to a Massachusetts directive implementing an overnight curfew on certain businesses, Encore Boston Harbor limited its daily operating hours and temporarily closed the hotel tower. On January 25, 2021, the limitations on operating hours were lifted, and Encore Boston Harbor restored certain operations and reopened its hotel tower on a Thursday through Sunday weekly schedule. The protective measures, including capacity restrictions, are still in place. The Company is currently unable to determine when the remaining measures will be lifted. 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 December 31, 2020, the Company had total cash and cash equivalents, excluding restricted cash, of $3.48 billion, and had access to $117.9 million of available borrowing capacity from the WRF Revolving Facility and $343.5 million of available borrowing capacity from the Wynn Macau Revolving Facility. The Company has suspended its dividend program and has postponed major project capital expenditures. In addition, the Company raised $842.5 million in an equity offering in February 2021. Given the Company's liquidity position at December 31, 2020 and the steps the Company has taken as further described in Note 7, "Long-Term Debt," the Company believes it is able to support continuing operations and respond to the current COVID-19 pandemic challenges.
