Uh, Marina, despite the fact that people have used the "poor family" routine as an excuse, there actually *are* quite a lot of poor families in the world, and a lot of people working overseas--including on cruise ships--to send money home to them.
Cruise ship crew members work seven days a week straight through for 10 1/2 to 11 months a year, then get a month or six weeks off in one chunk, so they see their families, kids, etc. only once a year. Yes, they have free room and board, but not a lot of time to enjoy it. They don't spend a lot of time "sitting back and enjoying the sunset," as you claim on another thread, because they're working from soon after daybreak until late at night with a couple hours off during the day. If you truly think these folks have it easy, I urge you to trade places with one of them for a while--do enjoy your new career.
