We recently did the Carnival Conquest on Southern Caribbean cruise out of Ft Lauderdale.
Day at Sea, Grand Turk, Dominican Republic (La Romona), Curacao, Aruba, 2 days at sea.
This is either our 5th of 6th cruise, with one on Norwegian and the rest on Carnival
Basic cabin, everything worked. Location at the last cabin at the back of the boat on the lowest deck was a concern going into the cruise, but worked out fine, although it was a bit of hike for certain things like the gangway on port days when its all the way in the front.
