bahamas day cruise isn't like any other bigger cruise ships out there. more of a bc ferry but with optional to get rooms. NCL, RCCL, Carnival, Princess has 3-4 days cruise to the bahamas. or to their private cruise line island in the bahamas. bigger way nicer ships tho.. so more $$. but service and food is guranteed to be good tho.
there's always d-wade from miami heat hehe
