Marriott Bonvoy: Book Hotels

What it does

Marriott Bonvoy: Book Hotels is a travel app for searching and booking stays across Marriott International’s hotel portfolio. It suits both occasional travellers who want to manage a reservation in one place and frequent guests who use Marriott Bonvoy membership, points and stay benefits.

Booking and stay management

The app covers more than 35 hotel brands and over 9,000 properties in more than 130 countries. Search tools help you compare destinations, dates and hotel options, while the account area keeps upcoming and past stays together. It also includes travel ideas and road-trip planning features for users who have not settled on an itinerary.

• Book rooms directly through Marriott’s hotel network.
• View reservations and manage parts of an upcoming stay.
• Track Bonvoy membership activity and rewards.
• Use mobile check-in where the participating property supports it.

Features that depend on the hotel

Some functions are available only at selected properties. Mobile Key can let eligible guests use their phone to enter a room, while in-app messaging can be used for requests such as extra towels or toiletries. Notifications may also provide updates during a stay, including when a room is ready. These features are useful, but they should be treated as property-dependent rather than universal parts of every booking.

Who it suits

This is a sensible choice for guests who regularly stay at Marriott properties or want access to a large, recognisable hotel network without switching between separate booking and loyalty tools. Travellers who rarely use Marriott hotels may find less value in the rewards features, although the booking and reservation tools remain relevant.

Marriott International is the listed developer. The app has a 4.87/5 rating from 498,963 reviews and 10,000,000+ installs, indicating broad use alongside its extensive property coverage.
