Real Estate Investments, Net [Abstract]
Investments In Real Estate	Investments in Real EstateDuring the nine months ended September 30, 2020, 50 hotels were sold for gross proceeds of $226 million resulting in a gain on sale of $59 million. In addition, during the nine months ended September 30, 2020, one hotel was disposed by returning the property to the ground lessor at the end of the lease term.      For the nine months ended September 30, 2020 we recorded an impairment loss of $54 million primarily due to lower valuation of certain of our properties related to the ongoing and updated impact of the COVID-19 pandemic on the lodging industry. We had no impairment loss for the three months ended September 30, 2020. We had no impairment loss for the nine months ended September 30, 2019. We will continue to monitor events and changes in circumstances related to our real estate assets, including updated COVID-19 pandemic data and effects, analysis related to our operations, fair value, our holding periods and cash flow assumptions, that may indicate that the carrying amounts of our real estate assets may not be recoverable. Such changes in circumstances and analysis may result in impairment losses in future periods.     As of September 30, 2020, we have not recognized any potential insurance claims related to COVID-19 pandemic losses. Given the contractual uncertainty of those claims, we cannot provide any assessment of whether such claims are realizable. Construction in progress primarily includes capitalized costs for ongoing projects that have not yet been put into service.
