Just back from a trip on the Carnival Dream, Dec 2012. The highlights of entertainment was Imani in the piano bar and an Asian couple that were very good. The boat was nice, but we were disappointed with the SPA/Gym and Entertainment.
The most frustrating was with aerobics section in the SPA. Regardless of how many people were taking a class (only 1) the entire section was closed off. They wanted to cram us all together in front of the ellipticals, no room. This was the only time I've been denied space. Waste of space and resources. The staffs excuse was "they paid for the class." So did they also pay for the only large area available for aerobics and stretching? I don't need help with Detox or to be shown how to do a sit-up. Just give me space. I also paid to be there. Too much limitation, without a reason. Would not open it up to "regular" passengers. Had to pay extra for a class. NOWAY
The Carnival Dream were also very quick to close down the buffet in the afternoon when we were getting back from excursions.
Cabin 9404 on Carnival Dream was too the back of the ship, Very noisy with the carts, but otherwise ok. would recommend getting a cabin in the middle or toward the front.
