Assuming you are on the young side 20s-30s
you may prefer Carnival which is know as the "Fun Ship"
I recommend Conquest. We recently did 5 days on the Elation and it went to Grand Turks,(Party at Margaritaville) Half Moon Cay (relax on this private island beach)and Nassau (Visit Paradise Island). We had an awsome time! But BEWARE! Cruising is addicting!
