Gatotom has it right. My folks roll that way.
The one cruise I went on was hell. To add to it, my then engagement was on the outs and my fiancee was being a PITA on the cruise. Since she had never had a job before, she thought it was really neat to have to dress up for dinner.
I bought a Tom Clancy book in the gift shop, some duty-free Dunhills and escaped to read on a secluded part of the deck. The other part I enjoyed was talking with a lot of the food crew, as they were almost all students from eastern Europe, where I've done a lot of travel. They all had their hometowns on their nametags and I spent a lot of time talking with them. Really enjoyed that, despite the fact that I usually hate all people.
