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 hotels with efficient operating models primarily in the Upscale segment of the lodging industry. At June 30, 2021, our portfolio consisted of 72 hotels with a total of 11,288 guestrooms located in 23 states. As of June 30, 2021, we own 100% of the outstanding equity interests in 61 of our 72 hotels. We own a 51% controlling interest in 11 hotels through a 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 hotels. Accordingly, all of our hotels are leased to our taxable REIT subsidiaries (“TRS Lessees”). Risks and Uncertainties The Company is subject to risks and uncertainties as a result of the effects of the novel coronavirus, designated as COVID-19 (“COVID-19”) and its variants, for at least the near future. The Company first began to experience effects from COVID-19 in March 2020, when the World Health Organization (“WHO”) declared a public health emergency of international concern related to COVID-19. By March 31, 2020, stay-at-home directives had been issued in many states across the United States and many local jurisdictions had additionally required the temporary closure of businesses deemed to be non-essential. These actions and restrictions have 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. These conditions resulted in a substantial decline in our revenues, profitability and cash flows from operations beginning in March, 2020. The COVID-19 pandemic caused the Company to temporarily suspend operations at six hotels containing 934 guestrooms in March 2020. An additional nine hotels, containing 1,278 guestrooms, each of which is adjacent to another of our hotels ("Sister Properties"), continued to accept reservations, but guests were directed to Sister Properties. In May of 2020, five hotels containing 682 guestrooms and four hotel properties adjacent to Sister Properties containing 506 guestrooms were re-opened. During the second half of 2020, three hotel properties adjacent to Sister Properties containing 430 guestrooms were re-opened. During the second quarter of 2021, one hotel containing 252 guestrooms and one hotel property adjacent to Sister Properties containing 202 guestrooms were re-opened. As of June 30, 2021, guests at one hotel containing 140 guestrooms are being directed to Sister Properties. During the first two quarters of 2021, we experienced sequential improvement in our business driven primarily by leisure travel. The improvement was the result of a steady decline in COVID-19 cases following the administration of vaccines and the easing of government restrictions and guidance in many jurisdictions. A recovery in business travel and group business has been slower to date. We anticipate that continued improvement in operating trends will be dependent on continued growth in leisure travel and a recovery of business travel. More broadly, a return to normalized levels of operations is dependent upon the dissipation of concerns related to COVID-19 and its variants, continued easing of government restrictions and guidance, restoration of consumer confidence, and a recovery in hospitality and travel-related demand. Beginning in March 2020, the Company took several actions to reduce costs and increase liquidity to mitigate the effects of the COVID-19 pandemic on the Company. We continue to engage in certain steps to reduce costs while taking appropriate actions to maintain guest safety and satisfaction. For additional information concerning such actions taken in response to the effects of the COVID-19 pandemic on our business, please see our Annual Report on Form 10-K for the year ended December 31, 2020. It is currently extremely difficult to predict the length of time it will take for us to return to pre-pandemic operational and financial performance. Despite the uncertainty, based on the actions we have taken, we believe we have sufficient cash and access to liquidity to meet our obligations for the foreseeable future.
