Having acquired Starwood Hotels & Resorts in 2016, Marriott International is the world’s largest hotel group, overseeing 6,700 hotels across more than 130 countries and territories. Among the largest of Marriott’s 30 brands are its Courtyard and Fairfield Inn select-service badges as well as its Marriott and Sheraton brands. This year, Marriott officially merged its Marriott Rewards loyalty program with the Starwood Preferred Guest platform. The newly integrated program, which concurrently added Marriott’s Ritz-Carlton Rewards to the mix, is now one of the largest, with more than 110 million members.
