We used this app on our most recent Disney Cruise and it was fabulous! We were able to communicate with each other from anywhere on the ship and it was so much easier to use than the wave phones. We would use the paper copy of the Navigator to decide what activities we wanted to do on board and put them on our favourites list in the app. Then, it would send us reminders right before the event-so handy! Finding anything on the ship was easy with the maps of each deck on the app. We all had fun looking at the dinner menus in advance and trying to decide what we wanted to eat later that night. This app just made everything so convenient! I would highly recommend it!
