I had cruised on the Carnival Triumph a couple years ago, and we loved it, so we thought we would try the Liberty, since it was going to a new island that I had not visited, Tortola, BVI.
The Carnival Liberty is a nice large ship with a lot of color and design. To some people it may be too much. One thing that is neat is the floor/deck number is in the carpet, so you know where you are located at.
They have some unique bars/discos/in design. They are made like batteries/cameras,hands/feet, and another piano. They are just unique in design.
