Yes, Sheraton is a core brand within the Marriott Bonvoy portfolio. Following Marriott International’s acquisition of Starwood Hotels & Resorts in 2016, Sheraton became one of the largest and most prominent brands under the Marriott umbrella. As part of the Marriott Bonvoy loyalty program, guests staying at Sheraton properties can earn and redeem points, enjoy elite status benefits (such as room upgrades, late checkout, and lounge access), and utilize the Marriott Bonvoy mobile app for check-in and digital keys. Sheraton is categorized by Marriott as a "Premium" brand, sitting alongside other well-known names like Westin, Marriott Hotels, and Renaissance Hotels. It is designed to serve both business and leisure travelers with full-service amenities, including "Sheraton Club" lounges, fitness centers, and on-site dining. The brand has recently undergone a global transformation to modernize its aesthetic and emphasize "community hubs" within its lobbies. Whether you are staying at a Sheraton Grand or a standard Sheraton, the stay will contribute directly to your Marriott Bonvoy account balance and elite night credits.
