Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization DiamondRock Hospitality Company (the “Company” or “we”) is a lodging-focused real estate company that owns a portfolio of premium hotels and resorts. Our hotels are concentrated in key gateway cities and in destination resort locations, and the majority of our hotels are operated under a brand owned by one of the leading global lodging brand companies (Marriott International, Inc. (“Marriott”) or Hilton Worldwide (“Hilton”)). We are an owner, as opposed to an operator, of the hotels in our portfolio. As an owner, we receive all of the operating profits or losses generated by our hotels after we pay fees to the hotel managers, which are based on the revenues and profitability of the hotels. As of March 31, 2020, we owned 31 hotels with 10,102 guest rooms, located in the following markets: Atlanta, Georgia; Boston, Massachusetts (2); Burlington, Vermont; Charleston, South Carolina; Chicago, Illinois (2); Denver, Colorado (2); Fort Lauderdale, Florida; Fort Worth, Texas; Huntington Beach, California; Key West, Florida (2); New York, New York (4); Phoenix, Arizona; Salt Lake City, Utah; San Diego, California; San Francisco, California (2); Sedona, Arizona (2); Sonoma, California; South Lake Tahoe, California; Washington D.C. (2); St. Thomas, U.S. Virgin Islands; and Vail, Colorado. Our hotel located in St. Thomas, U.S. Virgin Islands, Frenchman's Reef & Morning Star Beach Resort (“Frenchman's Reef”) is closed as a result of damage caused by Hurricane Irma in September 2017. We conduct our business through a traditional umbrella partnership real estate investment trust, or UPREIT, in which our hotel properties are owned by our operating partnership, DiamondRock Hospitality Limited Partnership, or subsidiaries of our operating partnership. The Company is the sole general partner of our operating partnership and owns 99.6% of the limited partnership units (“common OP units”) of our operating partnership. The remaining 0.4% of the common OP units are held by third parties. See Note 5 for additional disclosures related to common OP units. COVID-19 Pandemic and Management's Response In March 2020, the World Health Organization declared the novel coronavirus, or COVID-19, a global pandemic. Since then, the virus has continued to spread throughout the United States and globally. As a result of the pandemic, government mandates and health official recommendations, the demand for lodging has materially decreased. We have suspended operations at 20 of our hotels, and the hotels that remain open are operating at historically low occupancy levels. As a result, the COVID-19 pandemic had a negative impact on the operations and financial results of the Company for the quarter ended March 31, 2020. The severity and duration of the COVID-19 pandemic cannot be reasonably estimated at this time, but we expect it to ultimately have a material adverse impact on our results of operations, financial position and cash flow in 2020. We have taken aggressive steps in order to mitigate the ongoing operational and financial impacts on our business. We have fully drawn down on our $400 million senior unsecured credit facility, suspended our quarterly dividend commencing with the first quarter dividend that would have been paid in April 2020, canceled or deferred a significant portion of our capital expenditures planned for 2020, paused the reconstruction of Frenchman's Reef and reduced corporate expenses through decreases in executive compensation, employee headcount and other expenses. Additionally, in coordination with our hotel operators, we have developed and implemented action plans to significantly reduce operating costs at each of our hotels. As of March 31, 2020, the Company had unrestricted cash of $387.8 million. We have evaluated the current business environment and its effect on our results of operations, the actions we have taken and the other options available to us and have determined that we have sufficient liquidity in the event of a prolonged decline in hotel demand without issuing additional equity, obtaining debt financing or selling properties. Although we are in compliance with the financial covenants of our debt as of March 31, 2020, we have determined that it is probable the continuing effect of the COVID-19 pandemic on our hotel operating results will lead to our inability to satisfy certain financial covenants under the credit agreements for our senior unsecured credit facility and unsecured term loans beginning with the quarter ending June 30, 2020. If we were to violate a covenant, the lenders have the right to declare us in default and require repayment of the outstanding amounts under the credit agreements. We are in negotiations with our lenders to obtain a waiver of the financial covenants prior to any violation. However, because any required waiver would be granted at the sole discretion of the lenders, and such waivers may not be granted, there is substantial doubt about the Company’s ability to continue as a going concern, within one year from the date of these financial statements, without additional equity or debt financing or property sales. As of May 11, 2020, we have a term sheet for an amendment to our credit agreements that provides for covenant waivers for the subsequent four quarters through March 31, 2021 and certain other modifications to the covenants thereafter. We expect the amendment to be approved by a majority of our lenders and executed prior to any covenant violation, although we can provide no assurances that such amendment will be executed. If we are successful in obtaining the waivers, the substantial doubt about the Company's ability to continue as a going concern without additional equity or debt financing or property sales will be removed. The consolidated financial statements do not include any adjustments that would be required if the Company were not to continue as a going concern.
