Host Hotels & Resorts' luxury hotels form a constellation of stars. It's the nation's largest hospitality real estate investment trust and one of the top owners of luxury and upscale hotels. It owns about 105 luxury and "upper upscale" hotels mostly in the US, but also in Canada, Australia, New Zealand, Chile, Mexico, and Brazil, totaling some 56,000 rooms. Properties are managed by third parties; most operate under the Marriott brand and are managed by sister firm Marriott International. Other brands include Hyatt, Ritz-Carlton, Sheraton, and Westin. To maintain its status as a real estate investment trust (REIT), which carries tax advantages, Host operates through majority-owned Host Hotels & Resorts LP.
