We've been on 5 Celebrity cruises (about 15 total) , three on Aqua Class. We've been on this class of ship before so we knew where everything was located and what to expect. The Aqua Class experience is awesome. The ship is a bit older but still beautiful, the staff was unfailingly friendly and helpful. We've been to Key West and Cozumel several times and the excursions are spot-on. The shows were first-rate as always. I don't know whether part of the Hollywood-themed show should have included the Titanic (on a cruise). I didn't care but it creeped out the lady next to us.
We were disappointed in the lack of lounge music. There's always been music in the ship - a piano player in the piano bar, a guitar player and, once, a traveling A cappella group. Not this trip. There was no lounge music at all. On our last cruise they made a point that other cruise lines were cutting out live music, but not Celebrity. Well, the cuts are here. The "house band" was bass/guitar/drum/singer; there was a latin group and (surprisingly) a duo with techno-pop on a computer and live(!) snare drum set. This stretches the definition of "music" to the breaking point.
