We love the Carnival Legend the best. We feel that the Spirit Class ships are laid out the best, so easy to get around. Our second choice would be the Carnival Triumph. We just love the decor on that ship.
I am familiar with all five classes (Holiday, Fantasy, Spirit, Destiny & Conquest). Before Labor Day this year I will have also cruised on all five classes. My favorite is the Spirit class. It is large enough to have all the bells and whistles yet it is not overwhelming. It is also the easiest of the five classes to navigate, as it does not have a restaurant in the center of the ship that obstructs movement between the front and the back of the ship.
Carnival Glory!!!! It leaves out of the Best Port and it will take you to either Eastern or Western Carib. It is a wonderful ship it's big and Very Beautiful!!! We just went on Legend it was very beautiful also and we had a wonderful time, we loved all the ports of call, we just did not like Port of Tampa, too busy we would rather leave out of Cape Canaveral!!! We just chose to leave out of Tampa to do something new. I'm sure whatever ship you chose you will have a wonderful time Carnival is a great cruise line, this was my 5th cruise, Carnival Rocks!!!!
I would have to say, The One I'm On at the time. :lol I've been on the Triumph twice, the Conquest and the Valor. Didn't really see much difference. The next is the Inspiration, it's a smaller ship, Fantasy class I believe, so I'll see come December.
Our favorites would probably be the Ecstasy and the Conquest. We love the Fantasy class ships and the Conquest class ships. Elation and Glory would be in there, too since they are the same class as the Ecstasy and Conquest, respectively. Love them both for different reasons.
Although she will not likely be around much longer, we love the Holiday! We like small and intimate, or at least that feeling. The Spirit Class is definitely our next choice; love those corner aft suites!
