Our stateroom was nice and kept clean. The balcony's were regularly cleaned. It's sometimes difficult to be a non smoker and have a balcony downwind from a smoker, but I wouldn't let that stop you from booking a balcony room. It would just be nice to have the sides separated.
The decor, as some have mentioned is...odd. It wasn't to our taste but it didn't ruin the cruise for us. It's not everyday that one sees red snakeskin print in a dining room...
Chairs in the adult section of the ship were difficult to come by. We weren't able to sit in that particular section once on our cruise. We didn't have trouble finding chairs anywhere else though.
We tried several nights to watch movies on the large outdoor screen, but the cruise director was constantly making speeches during the movie, so we stopped trying. It's annoying to be in the middle of a scene and have the sound cut out only to hear chitter chatter and whoo hoo's.
We found that the daytime activities were somewhat lacking. There was rarely anything new or different. BINGO lovers will be in heaven though! A few things we found odd...they close the mini golf every night at 6pm until midnight, and there's a giant window (skylight) in the middle of the basketball court. The gym was nice, and had a GREAT steam-room with a floor to ceiling window. Beautiful.
Overall, the ship was clean and the itinerary was great but we felt that it wasn't really a cruise for an "active crowd". We won't be cruising Carnival again, but only because you do get what you pay for, and we're willing to pay a little more after our experience.
