Marriott Hotels is now offering mobile check-in at 329 properties throughout the continental U.S. and Canada, via the Marriott Mobile app. Marriott Rewards members can check in as early as 4 p.m. the day before arrival using the app, and then proceed to  an expedited desk at the hotel to pick up their ready-and-waiting key cards. Marriott began testing the app at 31 properties three months ago; one-quarter of Marriott Rewards guests with reservations at those participating hotels used the app to check in during that time. The free app is available for Apple iOS and Google Android devices. Marriott intends to introduce mobile checkout in November. At the end of November, the hotel company will begin testing mobile check-in in 15 other countries, including the U.K., China, United Arab Emirates, Mexico and India. Additional mobile features, such as housekeeping and wake-up call requests, are currently being tested at four Marriott properties.
