While both are now part of the Marriott International portfolio, Marriott and Sheraton occupy different "brand personalities" within the premium segment. Marriott Hotels is the flagship brand, often positioned as the "modern business" choice. It focuses on sophisticated, clean designs and technological innovations like the "M Club" lounge and mobile check-in to cater to the efficient, tech-savvy traveler. In contrast, Sheraton—which Marriott acquired through the Starwood merger—is positioned as "The World's Gathering Place." Its recent brand refresh focuses on community and "public space" luxury, featuring open, lounge-like lobbies with community tables and soundproof booths designed for collaboration. Historically, Sheraton was a pioneer in international expansion, being the first major US chain to operate in China, which gives it a legacy of "grand hotel" prestige in many global cities. Generally, you can think of Marriott as being slightly more "corporate and streamlined" and Sheraton as being more "community and heritage" focused. While both offer a high level of service, Marriott is often viewed as the flagship for modern convenience, while Sheraton aims to be the social hub of its destination.
