The term 'CRUISE SHIP LEVELS' refers to the various DECKS of a cruise ship. Cruise ships typically have multiple DECKS, each with its own purpose and amenities. The most common DECKS are the main deck, which is the lowest level and contains the cabins, dining areas, and other public spaces; the upper deck, which is the highest level and contains the bridge, crew quarters, and other service areas; and the promenade deck, which is in between the main and upper DECKS and contains the pool, spa, and other recreational areas.
