This past year saw the highest occupancy rate for all Washington, D.C. hotels in a decade. The D.C. Office of Revenue Analysis analyzed data from May 2005 to May 2015 and discovered that this growth was attributed to the new Convention Center hotel’s first full year as well as the year-over-year exponential growth in demand for hotel rooms in Washington, D.C. Industry data company STR, Inc. determined that the 12-month year ending in May 2015 saw 6.2 percent higher hotel demand than the previous year, with a total 77.3 percent occupancy.
