There's a first-person account of working in gift shop aboard a cruise ship on the IOJobs website. The female writer says she works aboard Celebrity Solstice and loves it. The article is worth looking at, but the writer loses a bit of credibility when she says that Celebrity Solstice is the largest ship in the world. (Celebrity Solstice is 122,000 grt, while Royal Caribbean Freedom-class ships are 154,407 grt.) That's also kind of in line with what she says about the job being rather easy and not taking much brainpower.
