I had taken a Caribbean Cruise last year on Celebrity's Mercury. The ship carried roughly 1/2 the passengers and I enjoyed my time on it. I took along paperwork from some projects I am working on and I find that the ship provides an excellent environment for such activity. Outside of Puerto Rico and Haiti I had been to the islands previously and I already had a taste of them. I wanted to see the actual country of Haiti (one of the poorest countries in the world) but Celebrity would not allow it. (The Cruise line owns a part of the island that is fenced off from the rest) If some of my fellow travelers were able to see how these people lived in Haiti there may have been less complaints.
The ship design was beautiful and it actually seemed less crowded than the Mercury(which was not crowded to me).
I understand that Celebrity is trying to "sell" their experience in order to sign up more people for it's cruises. There is some hype involved. There is going to be a difference between those who board the ship with "high expectations" and those who are just open to experiencing life as it unfolds.
Aqua 1537 is beautiful. There was plenty of hangup closet space but limited drawer space. Showers were fantastic. (took a picture to see if I could get one for my house). Its great that the comfortable bed run parallel to the balcony.A few time I did hear "banging" (service area nearby) nothing that awoke me (sound sleeper) and I did not consider it an issue.The thermostats in the room were excellent and there was no noise for the heat or AC. All good.
