Now that the ban has been lifted on Cuba, Carnival cruises is offering cruises there. I'm really thinking about doing this as the place intrigues me. I've read that no cars have been imported since the 1950's and that most of them are still running. It's like a time capsule and I would love to witness it first hand. Anybody have any thoughts? Would it be better to take the cruise which allows you to explore all day and stay the night or would it be better to just book a flight.
