Needs work!

I used the app on the Dream in May 2016.
The good: Chat was great. I put my phone on vibrate so I would get notification.
The bad: Did not work on Castaway Cay. The Disney-provided wave phone will work on the island but you dont want to lose it ($250 reimbursement fee) and it is not waterproof.
The ugly: Times specified were not all accurate. It said a couple of activities (bike rentals & post office) on Castaway Cay closed early in the day (11 a.m.) making us rush unnecessarily (actually closed at 4 p.m.). Also advised stores didnt open until 5-6 p.m. everyday. Sea day they were open all day. The dinner menus and deckplans were good. A little more information like breakfast & lunch menus would have been great and information on deckplan detours necessary when halls dont go through would have been great!
