There are 5 classes of ships from Carnival Holiday, Fantasy, Destiny, Spirit and Conquest. The newest and largest ships coming from the Conquest class such as Carnival Conquest, Carnival Glory, Carnival Valor and the new Carnival Liberty. Here is a website with tours and other information about the differant ships in each class.
Definately the conquest class I have been on Glory and celebration and soon to be the Valor! Out of the two so far with carnival it was Glory and I will have to say Valor will probably be right up there.
Tough question....each ship is so different. We have yet to be on the Destiny Class or Spirit class ships but will have been by the end of the year. I preferred the Conquest over the Glory...must have been the decor. The Celebration was my favorite of the three Holiday class ships. We've only been on 3 of the 8 Fantasy Class ships....It's a toss up between the Fantasy and the Elation. I guess the ship that really stands out in my mind (besides the Conquest because we were last on her) is the Carnival Victory.
Depends very much on what you like I would say. We have sailed the Conquest and prefer the old Inspiration, even with its wild neon/disco decor. Best ships for some will be the most mamoth ship, and others maybe the newest ship, or there may be a few like us who prefer the smallest ship that was least abused.
I have sailed the fantsy and the fascination,, after sailing the grand princess, i will be choosing the bigger ship to cruise on ,, some cruisers like the small ship feel,,,, for me the bigger the better... for us its all about the ship now, the ports are secondary, so if the ship is small i feel bored within a matter of a day
We have done the Fantasy class and the Spirt class. We loved the Miracle. However I really like the layout of the bars on the Fantasy class. The MIracle is much classier looking than the Fantasy class. We have done the Fantasy and the Sensation. The Miracle also has 1 dining room which is much better than the 2 dining room layout.
We like new ships.
