The Marriott Mobile App is part of an effort by the global hotel chain to make it easier for its guests to access a wide variety of services related to their stay.
The app, available on the Apple App Store in addition to Google Play and the Windows Phone Store, allows you to make your hotel reservations at nearly 4,000 hotels and resorts in 70 countries. Moreover, the use of the phone platform means that you can use GPS to find a hotel near you, in case you find yourself in a city without a place to stay.
The Marriott Mobile App also lets you access photos of hotels and view amenities so that you can get a full picture before going ahead and making a reservation. The app also makes checking in and checking out easier, and ultimately minimizes the time spent in dealing with the hotel so you can maximize your enjoyment of the hotel itself.
