The downturn in new U.S. hotel rooms coming online in 2009 should help set the stage for an industry recovery in the following year, a new report from PKF Hospitality Research finds. PKF-HR says a dip in the supply of additional rooms, stemming from cancelled and delayed hotel projects during 2009, will eventually increase demand, resulting in gains in occupancy and pricing power in 2010. But first, U.S. hotels will have weather one of the longest recessions in the history of the domestic lodging industry. PKF-HR is calling for a 7.8 percent drop in revenue per available room (RevPAR) for 2009; however, year-over-year quarterly increases in that indicator could take place as early as the second quarter of 2010.
