Starwood Hotels and Resorts announced Monday that 21,000 new hotel rooms opened at its properties in 2011, the largest organic growth in Starwood's history. Additionally, the hotel company inked 112 new deals this past year, the highest number since before the global economic crisis. In the coming year, more than 60 percent of Starwood's new hotels will be in the luxury and upper-upscale chain scale segments. Among them, the company will mark milestones with the 30th St. Regis hotel, the 80th Luxury Collection property and the 45th W hotel. Starwood's luxury hotel room count has grown by 75 percent over the past four years. Geographically speaking, nearly three-quarters of the company's new properties in 2012 will open outside of North America. "Markets like Brazil, Africa, the Middle East and Indonesia will be the ones to watch," noted Simon Turner, Starwood's president of global development. Mid-market brands also are performing well; the Four Points by Sheraton flag accounted for nearly a quarter of the company's openings and signings in 2011.
