Why do people go on cruises just to do all the things they can do on land?

@StaticNightmares that's a silly answer. They aren't expensive compared to what you pay for the same trip not by boat and the service is excellent. Anyone can spend money on things they can't afford, houses, cars, hobbies, drugs, alcohol, other types of travel. Don't put people in boxes. I would never have afford the experienced I had
If I had driven, paid for motels, food, seeing dolphins, birds, sun sets, meeting new people. Where I live its really expensive to travel to other places. A cruise package is one very affordable way. I will do a bigger one around u nd the Pacific islands when I save enough to do so.
