I have two main complaints: The hottubs were never warm the whole cruise except for the one in the spa. But then you got no sun. We mentioned this to several workers who only shrugged. The pools were also very cold especially the adult pool area. The lido deck pool finally got warm, but was always filled with kids. On every other cruise we've been on, we enjoy the hottubs every evening until late.
My other main complaint would be the evening entertainment. They had a great comedian one night and a very good juggler/comedian another night. The rest of the time was very lacking. No decent movies in one of the lounges or on the room tv's. Other than the main theater, the other lounges were either closed or no one was in them. Carnival should consider having "Movies under the stars". Also, the comedian shows were at 8:30 and midnight. Midnight is too late if you have an early excursion. This should be moved up to 10 or 11 and tell parents, children are not permitted.
Just a minor complaint: The poolside waiters were only interested in selling drinks and would never bring you just a coke. The poolside tables were also often dirty and would remain that way for hours. The chair hogs were in full force on seadays. Also the dining room was noisy with the way it's completely open. No romance in that atmosphere. I did enjoy the waiters "show time"! Disembarkment went smoothly.
