This is the sort of content I find fascinating. What's it like to live and work on board a ship? For a cruise ship, the answer is often "pretty good." For example, you'll occasionally need a haircut. This is the barbershop for crew members only on a Carnival-owned vessel.
Core 77 has a roundup of photos showing different crew-only areas of cruise ships, including mess halls, exercise facilities, and laundry rooms. Some of the crews have really nice amenities, including private pubs, weightlifting equipment, and pools that only they can access.
