Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS General Summit Hotel Properties, Inc. (the “Company”) is a self-managed hotel investment company that was organized on June 30, 2010 as a Maryland corporation. The Company holds both general and limited partnership interests in Summit Hotel OP, LP (the “Operating Partnership”), a Delaware limited partnership also organized on June 30, 2010. Unless the context otherwise requires, “we,” “us,” and “our” refer to the Company and its consolidated subsidiaries. We focus on owning premium-branded hotel properties with efficient operating models primarily in the Upscale segment of the lodging industry. At June 30, 2022, our portfolio consisted of 102 hotel properties with a total of 15,323 guestrooms located in 24 states. As of June 30, 2022, we own 100% of the outstanding equity interests in 61 of our 102 hotel properties. We own a 51% controlling interest in 39 hotel properties through a joint venture that was formed in July 2019 with GIC (the “GIC Joint Venture”), Singapore’s sovereign wealth fund. We also own a 90% controlling interest in two hotel properties that we acquired in June 2022 through another joint venture (the "Brickell Joint Venture"). We have elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes. To qualify as a REIT, we cannot operate or manage our hotel properties. Accordingly, all of our hotel properties are leased to our taxable REIT subsidiaries (“TRS Lessees”). During the six months ended June 30, 2022, the Operating Partnership and the GIC Joint Venture closed on a transaction with NewcrestImage Holdings, LLC, a Delaware limited liability company, and NewcrestImage Holdings II, LLC, a Delaware limited liability company (together, “NewcrestImage”), to purchase from NewcrestImage a portfolio of 27 hotel properties, containing an aggregate of 3,709 guestrooms, and two parking structures, containing 1,002 spaces and various financial incentives for an aggregate purchase price of $822.0 million (the "NCI Transaction"). In June 2022, the Operating Partnership exercised an option to acquire a 90% equity interest in the AC Hotel by Marriott and Element Miami Brickell Hotel in Miami, FL. (together the "AC/Element Hotel") based on a gross hotel option exercise price of $89.0 million (the "Brickell Transaction"). See "Note 3 - Investment in Hotel Properties, net" for further information. Risks and Uncertainties Beginning in March 2020, we experienced the negative effects of the novel coronavirus, designated as COVID-19 (“COVID-19”) and its variants (collectively, the "Pandemic"), which had a significant negative effect on the U.S. and global economies, including a rapid and sharp decline in all forms of travel, both domestic and international, and a significant decline in hotel demand. As such, we experienced a substantial decline in our revenues, profitability and cash flows from operations during the years ended December 31, 2020 and 2021. Additionally, there has been a sharp increase in inflation and interest rates during the six months ended June 30, 2022. The extended effects of the Pandemic and macroeconomic conditions may result in additional risks and uncertainties related to our business and our ability to recover to pre-Pandemic levels and beyond. During the three and six months ended June 30, 2022, we experienced significant improvement in our business, driven primarily by leisure travel and to a lesser extent modest improvement in other demand segments, including corporate and group. The improvement was the result of a significant increase in the availability and administration of vaccines globally as well as the easing of government restrictions and guidance in most jurisdictions. We anticipate that continued improvement in operating trends will be dependent on continued strength in leisure travel and a recovery of business travel. More broadly, a return to normalized levels of operations is dependent upon a continuation in the recovery of our business, further dissipation of concerns related to the Pandemic, geopolitical stability, moderating inflation, a normalized labor market, and maintaining a high-quality portfolio aligned with evolving guest preferences. For additional information related to the effects of the Pandemic on our business, please see our Annual Report on Form 10-K for the year ended December 31, 2021.
