@Cageybird- I'm glad your friend had a good time working on a cruise ship. I've heard other people have been disappointed with musician jobs on cruise ships, however. One of my cousins is a Broadway-style singer, and she found a listing for cruise ship entertainers on a campus bulletin board. She went to the location mentioned in the ad and auditioned for them. They offered her a great job as a cabaret singer on a Caribbean cruise.
Her actual experience was not so good. The cruise line actually wanted their entertainment staff to perform other duties as well, like serve in restaurants and work in the laundry room. They were supposed to perform two shows a night after working all day as regular crew. It was an exhausting experience for her, and she never tried it again. I think musicians and other entertainers should really do some research before looking at cruise ship jobs.
