Plinky asks, "Would you ever take a cruise? Why or Why not? Where would you go?"
Sure. I'd love to take a cruise. In fact, that seems like a lovely way to travel to/through the Caribbean or the coast of Alaska. I know people who have done both who recommend both trips highly.
I think I'd enjoy a theme cruise more, though, like gaming (RPG gaming, not gambling gaming) or filking or maybe even an entire SF Con on board a ship. I'm not particular to any one fandom enough to get into anything like a Trek cruise, but a more general fan cruise could be fun. Combine lovely surroundings and pampering with fun? Sure!
