The U.S. hotel industry continued to post year-over-year improvements, according to February statistics released by Smith Travel Research. Overall monthly increases were realized in occupancy (5.2 percent), average daily rate (2.5 percent) and revenue per available room (7.9 percent). Super Bowl-host Dallas led the way in terms of both average daily rate, which rose 22.7 percent over last year, and RevPAR, which skyrocketed by nearly 36 percent. Three additional markets enjoyed double-digit increases to February's average daily rate -- San Francisco/San Mateo, Calif.; Los Angeles-Long Beach, Calif.; and Oahu, Hawaii. Those markets also posted RevPAR jumps of more than 20 percent, as did Orlando. The luxury chain scale segment outdid all lesser properties, with significant increases to occupancy (6 percent), rate (5.6 percent) and RevPAR (12 percent).
