We prefer Celebrity, Disney, Princess for the Caribbean, and sometimes RCCL (Europe). Carnival has a European itinerary we are interested in. Haven't been on Carnival in 15+ years-we sailed on a brand new ship in Europe (great experience-similar to Celeb/Princess). This would be older ship. We are in our early 60s, active, enjoy wine/food, things like "fake" Beatles/rock stars concerts onboard, but not crazy, loud entertainment, belly flop contests, etc. We sailed on the oldest RCCL ship in Europe in an OV cabin this summer and it was fine, though we did eat in the buffet for dinner a few nights based upon MDR offerings. We are fine to lower our expectations for Europe, where the ports are the main focus and we're off the ship most days. We'd not have been as happy (on that older RCCL ship) if that was a Carib. trip with lots of sea days. For those who prefer Celebrity and have done Carnival in Europe, how did it compare?
