We are Disney veterans and do the parks almost every year so when we decided to go on a cruise Disney was the obvious choice. The service was beyond any we have ever had in the parks or hotels. The Cast members will do anything they can for you. There was always things to do so it's impossible to be bored. I never wanted to leave.
We stayed at the Hyatt at the airport the night before and it was very convenient, plus as we were taking the DCL bus they took our bags from our room for us.
The Dream is beautiful, even though it is big I learned my way around pretty quickly. there are CM's everywhere always there to help if you need it. There are little details everywhere. If you can always walk up to the next floor when the elevators are busy, also avoid the mid-ship elevators if you can.
We loved our stateroom, it makes great use of the space. The split bathroom is great. The pullout is very comfy and I slept great on it. You did feel a little vibaritions when pulling into port but it was not bothersome to me. It was a very quiet room and would book it again if it was available. There is lots of room under the beds as well.
Castaway Cay is beautiful, we rented a bike which was lots of fun. It's very nice to have the island just for the DCL guests.
