The ship is sparking and new (and huge), and the staff seem to work around the clock to keep everything clean. Although there were appx. 6,000 guest on board with us, I never really felt over-crowded (except on first day in Windjammer--but this is true for almost every cruise, because people camp out at tables waiting for cabins to become available instead of moving to a lounge, etc.).
I was in an oceanview balcony, and it was spacious and clean with plenty of storage (for two). The shower doors are rounded, creating a few extra cubic feet of space in the shower (Great idea!!).
The casino is huge and most of the casino is non-smoking, which I LOVED!!! I believe this is the first cruise (out of 50+) where I did not have to wash my hair and use a neti-pot rinse upon return from the casino at the end of the evening.
Some of the shows were unique to the ship, and most of the shows were very good. The only show that you could make reservations for was Pixels, and it was very good. If you want to see Pixels, I recommend making reservations so that you can get really good seats since guests with reservations are admitted first.
Ports of call were excellent!
