You work more than 10 hours a day, let me tell you. You're extremely lucky if you get eight hours off in a row to sleep. And forget getting time off in port! I once worked three months straight without one day off. When I finally got a day off, what did I do? I slept for 17 hours straight, no kidding. And it was a day off in Port Canaveral which wasn't exactly exotic.
True, you don't get to be on public decks, either. There's some activities down below for the crew...most of which involve getting drunk so you forget how you're tied to the ship. And unlike the guests, you don't easily get off of the ship when you've returned after the cruise to your home port. Cruise employees are given "windows" of time they can leave if customs allows them, which sometimes they don't, and there could only be three 10-minute windows a day before you ship out again. If you can't get through the exit line in 10 minutes, you're stuck on the ship. It's crazy, but true. Being a cruise employee isn't all that bad, but you also can't comprehend the living conditions until you've experienced it for yourself.
