It's just a way to sell bottom-rung vacations for top dollar. There are dozens of "travel agencies" hawking these same "deals." The "cruise ships" are actually ferries (probably SeaEscape or similar barges), and really old ones at that; the dinner is a low-budget buffet, and the accommodations are a cut below Motel 6 (if that's possible). A quickie Carnival cruise can wind up costing just about the same money (believe me, there are other charges to come, as in food on land, etc.). Turn and run - and don't look back!!
