Ok here it is! First off, Full Disclosure, we LOVE Disney and are DVC members. That being said it was also our FIRST cruise EVER. I will tell you the negative first so that my objectivity is intact! I would describe the cruise as FUN, not necessarily relaxing. I will explain why.
What I would do differently next time around. (Not ALL Disney's fault)
Firstly, I would not fly down on the am of the cruise. Took a 6am flight out of JFK and we had to be awake at 2:30 am. Embarked at 11:30 (group 2) that was nice because nobody was really on ship yet. I will also note that even though we were first on the ship, our luggage came last! That was frustrating. We were exhausted on night #1! (our fault though)
Cabin is excellent. Mid ship deck 7 no noise and beautiful verandah.
