Hi,
Just some word of advice, you need to be very careful before you decide to cruise with Carnival. The Spirit is in poor shape, in cabin furniture falling apart, gym equipment not working, mini golf course in tatters, broken doors and glass.
Be careful if your intending to bring a bottle of Alcohol along, it was my Wife's birthday and we intended to celebrate on board with a bottle of liquor, this was confiscated and was promised to be given back at the end of the cruise, instead they so called disposed of the bottle.
Cabin was small but tidy, stewards very very friendly and proactive.
