This app was very handy with a family of 7 all over the ship and no 4G service like we are used to. It was great to be able to text with the kids when they were off doing something else. (We wish we could still use the Disney emojis!!)
Being able to look at all the activities/menus was helpful too. If this app worked on Castaway Cay I would give it a 5.
