Did a back to back to east and west Caribbean. Loved pretty much everything about the ship but what I appreciated the most about it was the more subdued classic décor. Clean, classy, and without the hokey edge that some ships have. The crew was overall the best we've encountered with Carnival. If I had to find one point of criticism it would be the stateroom stewards. Ours was just okay, but nothing lacked that "at your service" attitude even after we tipped him nicely on the first day. Other passengers had reports ranging from "awful" to "never see ours." Regardless, we would sail on her again in a heartbeat.
Dinning room staff was amazing with my wife's special dietary needs, going way beyond what we asked or required. The Red Frog Pub was our favorite hangout spot, providing the real life local pub atmosphere we enjoy on shore, even offering Caribbean pub food served right in the pub (at a small additional $...$3 for most items) so if you're drinking a lot you don't have to go chasing down food somewhere else.
Biggest disappointment is no sports bar as most Carnival ships have, so it was a struggle to watch much football, etc. while there. Only place was the casino with the cigarette smoke and the Red Frog Pub.
Loved the room. However, didn't use the second bath much at all. Would be much more appreciated with a second toilet rather then just a second sink and tub.
