In the first quarter, despite what CEO Frits van Paasschen called "turmoil in North Africa and the Middle East and the devastating earthquake in Japan," worldwide revPAR -- or revenue per available room, a key metric in the hotel industry that multiplies a property's room rate by its occupancy rate -- jumped 10.4%. The metric was up 11.1% in North America. RevPar had suffered in recent years as cash-strapped travelers were unwilling to pay for high-priced hotel rooms, even at luxury level establishments. Starwood also offered an improved full-year profit guidance, or $1.60 to $1.70 per share, in line with analysts' expectations. "The outlook for the rest of the year looks promising as we view the events of the past few months as not having derailed the overall global economic recovery," van Paasschen said at the time.
