Dubai – For today’s global traveller, their smartphone is what links them to their world. To put even more power in the hands of travellers, Marriott Hotels, the flagship brand of Marriott International has expanded mobile check-in and checkout globally for Marriott Rewards members to nearly 500 hotels. This means Marriott Rewards guests from London to Dubai to Shanghai to Mexico City to New York can simply check-in and checkout using the wildly popular Marriott Mobile app on their smartphone. In the Middle East the application was initially rolled out in the UAE, Egypt and Jordan; following its success it is now available across 16 properties spanning the initial launch markets, Oman, Saudi Arabia and Qatar. How it worksWith the Marriott Mobile app, check-in and checkout is simple to use. Marriott Rewards members receive a push notification on their Apple iPhones or Android devices after 4 pm on the day before their arrival alerting them they can check-in. Then they receive an automatic notification when their room is ready. Because payment information is stored within members profiles, guests simply walk up to the expedited mobile check-in desk where their pre-programmed key card will be waiting for them. At the end of their stays, guests receive a push notification alerting them mobile checkout is available. Upon completion, guests will then be prompted to provide an email address where their bill will be sent, allowing them to bypass the front desk. “When we first began testing mobility, we went straight to the experts, our guests, who told us they wanted the power to check-in and checkout on their smartphones,” said Paul Cahill, senior vice president of brand management for Marriott Hotels. “Among Millennials, nine out of ten who tried mobile check-in and checkout for the first time gave it high marks and said they would use it again for their next stay.”You can download the Marriott Mobile app from the Apple iTunes Store, Google Play.
