If you mean the kind of passenger ship sailing on the sea, which is a large luxury holiday, it is called a "cruise ship" instead of a "cruise ship". English is cruising.

Cruise rooms are divided into three types: inner cabin (without windows), outer cabin (with windows) and balcony room, all of which have separate bathrooms. Most rooms are standard rooms with one double bed or two single beds, but some cruise standard rooms have sofabeds or folding beds, which can sleep a third person or even a fourth person. In addition, there will be a small number of suites on board.

There are many restaurants (including large cafeteria and ordering restaurant), bars, theaters, outdoor swimming pools, game halls, gyms, basketball courts, casinos (not all cruise ships depend on local laws), libraries, spas and so on.
