The app is actually utilized to make all of your bookings for the restaurants onboard as well as room service. If you shake your phone, while the app is opened, champagne magically shows up where you're at. There are going to be even more fun innovations like that on there as well. You'll get alerted of fun events happening and it allows more interactions with the sailer onboard. There are no phones in the cabin. Anything that can be done onboard is used through the app.
