The only reason to upgrade to the Aqua Class is for the shorter line at check in. The "suites" are not multi-room, and the view is obstructed by the overhang of the deck above. It is, seriously, an obstructed view. And, since you are on deck 9, you get noises from the pool deck above all night long. Must be why all of the real suites were moved to deck 6.
The bathrooms are nowhere near Disney Cruise Line standards as every surface touches you as you shower.
The food at the buffet is substandard as it was always cold, even though we were first in line for breakfast.
And don't buy the drink package, as there are very few bars that are open to buy a drink. Going to the theater? No bar in that half of the ship. It literally takes a walk through half of the ship to get a drink!
Standard cabin, nothing special.
