hop in a pool suspended five stories above another pool on the deck of a ship that looks like the result of a mad scientist hybridizing the genes of an airport duty free terminal, a private athletic club, a five-over-one and the Evergreen Ever Given (with just a splash of Six Flags for flavor)
I think you do leave on most cruises. They stop in different port cities potentially in different countries. At least the best ones probably do.
Yeah, from what I've seen, the port stops are the main attraction and the ship amenities are generally just there to tide you over between.
