It’s much nicer than a rabbit hutch. I like going somewhere without having to be the driver, having someone else handle the food and the cleanup. It does bother me that the really big cruise ships are floating cities, but generally cruises are pleasant.
I like road-tripping in the family car, also, but then I have a lot of responsibility for the safety and happiness of my fellow travelers. So, a cruise is a nice change of pace.
Everyone is different. It is about a thousand a day for that.
