Mobile technology is changing the hospitality industry by allowing guests to have better communication and service through their phones. Major hotels like Marriott and Walt Disney World Resort now offer mobile apps that let guests check-in, use their phone as a room key, request services, view fast passes, photos and payments, and customize experiences like booking and managing family calendars. As the world changes and life moves faster, mobile services in hospitality aim to save guests time while keeping them engaged and empowered to control their experience on their own terms.
