Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Policy Text Block]	Gross casino revenue is the aggregate of gaming wins and losses. The commissions rebated to junket operators and premium players for rolling play, cash discounts and other cash incentives to patrons related to gaming play are recorded as a reduction to gross casino revenue. Gaming contracts include a performance obligation to honor the patron’s wager and typically include a performance obligation to provide a product or service to the patron on a complimentary basis to incentivize gaming or in exchange for points earned under the Company’s loyalty programs. For wagering contracts that include complimentary products and services provided by the Company to incentivize gaming, the Company allocates the relative stand-alone selling price of each product and service to the respective revenue type. Complimentary products or services provided under the Company's control and discretion, which are supplied by third parties, are recorded as an operating expense. For wagering contracts that include products and services provided to a patron in exchange for points earned under the Company’s loyalty programs, the Company allocates the estimated stand-alone selling price of the points earned to the loyalty program liability. The loyalty program liability is a deferral of revenue until redemption occurs. Upon redemption of loyalty program points for Company-owned products and services, the stand-alone selling price of each product or service is allocated to the respective revenue type. For redemptions of points with third parties, the redemption amount is deducted from the loyalty program liability and paid directly to the third party. Any discounts received by the Company from the third party in connection with this transaction are recorded to other revenue. After allocation to the other revenue types for products and services provided to patrons as part of a wagering contract, the residual amount is recorded to casino revenue as soon as the wager is settled. As all wagers have similar characteristics, the Company accounts for its gaming contracts collectively on a portfolio basis versus an individual basis. Hotel revenue recognition criteria are met at the time of occupancy. Food and beverage revenue recognition criteria are met at the time of service. Convention revenues are recognized when the related service is rendered or the event is held. Deposits for future hotel occupancy, convention space or food and beverage services contracts are recorded as deferred income until the revenue recognition criteria are met. Cancellation fees for hotel, meeting space and food and beverage services are recognized upon cancellation by the customer and are included in other revenues. Ferry and entertainment revenue recognition criteria are met at the completion of the ferry trip or event, respectively. Revenue from contracts with a combination of these services is allocated pro rata based on each service’s relative stand-alone selling price.
