I am a single traveler, 45 years old, male, and usually willing to pay a bit more for superb service. The cruise was great, but there was nothing particularly "superb" about this cruise.
My travel group consisted of 26 acquaintences in 14 cabins, ranging from AquaClass on Deck 9 to Deck 2 with a window. I was in AquaClass, cabin 9100, which was right at the bottom of the stairs, next to the cyber-cafe. Everyone had at least the Classic Beverage Package, and I was on the Premium Beverage Package.
The shower tower was wonderful
Dinners at Blu were very nice, although not my typical preferred fare
The Brunch in San Marcos was very good
Cozumel felt like a depressed third-world country
The bar staff was both understaffed and inexperienced
The craps table was only open about half the posted casino hours
Several AquaClass people didn't have a "pillow menu" in the cabin
LGBT meet/greet was removed from the daily schedule and only reappeared when I questioned its disappearance
Celebrity literature states that you'll be contacted by your spa concierge when staying in AquaClass. None of us were ever contacted by any spa concierge, in fact I felt like an outsider when I toured the spa on embarkation day. Yes, they asked if I'd be interested in a shave, but then it went downhill from there. I finally turned around and walked out.
