Room revenue for U.S. hotels will rise 8.1 percent in 2011, according to PKF Hospitality Research, and climb another 6.1 percent next year. That said, RevPAR results will vary according to tier and location, noted the company's December edition of Hotel Horizons. In examining the occupancy forecast, PKF-HR expects a much greater surge among the luxury, upper-upscale and upscale hotel segments (all of which should achieve more than 70 percent occupancy) than among the lower-priced segments, which likely will see levels below their long-term averages through 2013. More aggressive pricing is expected, with the average daily rate predicted to go up 4.7 percent for this year and another 5.3 percent in 2012 -- again, with less significant increases among lower-tier properties. While some hotels will struggle, the report notes, the overall forecast is optimistic. "We remain quite confident that 2012 will be another favorable year of growth for U.S. hotels," noted PKF-HR president R. Mark Woodworth.
