Since joining Marriott International as part of the acquisition of Starwood Hotels and Resorts in September 2016, Sheraton has exited 6,000 rooms with another 2,000 expected to depart by the end of the year. During the same period, 5,000 rooms have been signed to the portfolio.

Sheraton is part of the largest merger in hospitality history, which occurred when Marriott International acquired Starwood Hotels & Resorts Worldwide. The deal was finalized in September 2016 for approximately $13 billion. This merger brought Sheraton, along with other iconic Starwood brands like Westin, W Hotels, and St. Regis, under the Marriott umbrella. In 2026, the merger is fully integrated, and Sheraton is a key pillar of the Marriott Bonvoy loyalty program. While Marriott has been revitalizing the Sheraton brand with a new, modern "town square" design concept to distance it from its older, more traditional image, the brand remains a global giant with hundreds of properties that benefit from Marriott's massive distribution network and operational scale.
