I've worked on cruise ships for over six years, so I'm familiar with how the crew lives on board. Staffers typically live with a roommate in tiny cabins that have bunk beds and small closets. We usually eat at our own buffet and hang out after work at the crew bar.

Yes, the vast majority of cruise ship staff and lower-level crew members share cabins, which are typically small, windowless rooms located on the lower decks of the ship. These "crew cabins" usually feature bunk beds, a small shared bathroom, a desk, and limited storage space for two people. Sharing a room is a standard part of ship life and is one of the biggest adjustments for new crew members, as it offers very little privacy. However, cabin assignments are usually hierarchical. Entry-level staff like waiters, cleaners, and entertainment crew almost always have roommates. Mid-level managers and supervisors might be assigned a single cabin, though these are still very compact. The highest-ranking officers, such as the Captain, Chief Engineer, and Hotel Director, are provided with much larger, private "suites" that include separate living and sleeping areas and often windows or balconies. Despite the tight quarters, crew areas are self-contained "cities" with their own gyms, bars, and dining halls, fostering a close-knit community among the staff. For many, the social benefits and the ability to save almost 100% of their earnings outweigh the inconvenience of sharing a few square meters of living space.
