They were good. I was just on the Caribbean. I would say they were kind of 90's themed, and they've got soul. They played the parties on the top deck, and they did a better job of partying than we, the passengers did. Of all the house bands and singers on board, they were the best. Arguably better than the Princess theater singers, too--they were stiff; Xtasea was not.
Although...for the best instrumentalist, I have to go with the steel drums guy. It's the Caribbean Princess. That guy needed more bands behind him and stuff.
