The Marriott Rewards, The Ritz-Carlton Rewards and Starwood Preferred Guest were replaced in February with the launch of the Marriott Bonvoy app. The app was designed to make it even easier for people to search and book hotels across Marriott’s portfolio of 6,700 participating hotels across 30 brands in 130 countries, engage in mobile check-in (with an alert sent when the room is ready), use mobile key (in select hotels) to enter the room, submit mobile requests for service and amenities, and chat with representatives before, during, and after their stay.
