Equity Method Investments and Joint Ventures [Abstract]
Other Investments	Note 6. Other Investments Equity method investment As of September 30, 2022, we owned approximately 34% of Sonesta’s outstanding common stock. We account for our 34% non-controlling interest in Sonesta under the equity method of accounting. As of September 30, 2022 and December 31, 2021, our investment in Sonesta had a carrying value of $113,168 and $62,687, respectively. The cost basis of our investment in Sonesta exceeded our proportionate share of Sonesta’s total stockholders’ equity book value on the date of acquisition of our initial equity interest in Sonesta, February 27, 2020, by an aggregate of $8,000. As required under GAAP, we are amortizing this difference to equity in earnings of an investee over 31 years, the weighted average remaining useful life of the real estate assets and intangible assets and liabilities owned by Sonesta as of the date of our acquisition. We recorded amortization of the basis difference of $65 in each of the three months ended September 30, 2022 and 2021 and $195 in each of the nine months ended September 30, 2022 and 2021. We recognized income of $2,866 and $2,158 related to our investment in Sonesta for the three months ended September 30, 2022 and 2021, respectively, and income of $4,472 and $50 for the nine months ended September 30, 2022 and 2021, respectively. These amounts are included in equity in earnings of an investee in our condensed consolidated statements of comprehensive income (loss). We recorded a liability for the fair value of our initial investment in Sonesta, as no cash consideration was exchanged related to the modification of our management agreement with, and investment in, Sonesta. This liability for our investment in Sonesta is included in accounts payable and other liabilities in our condensed consolidated balance sheet and is being amortized on a straight-line basis through January 31, 2037, as a reduction to hotel operating expenses in our condensed consolidated statements of comprehensive income (loss). We reduced hotel operating expenses by $621 for each of the three months ended September 30, 2022 and 2021, respectively, and $1,863 for each of the nine months ended September 30, 2022 and 2021, respectively, for amortization of this liability. As of September 30, 2022 and December 31, 2021, the unamortized balance of this liability was $35,584 and $37,447, respectively. In March 2021, we funded a $25,443 capital contribution to Sonesta related to its acquisition of Red Lion Hotels Corporation. During the nine months ended September 30, 2022, we funded an aggregate of $45,470 of capital contributions to Sonesta related to Sonesta’s acquisition of a portfolio of four hotels located in New York, NY using cash on hand. We continue to maintain our 34% ownership in Sonesta after giving effect to these fundings.

Our TA shares had a carrying value of $63,896 and $61,159 as of September 30, 2022 and December 31, 2021, respectively.
