On one hand I don't like being around kids. On the other hand I'm a big fan of ocean liner history. So it's ironic for me that Disney did the best job of capturing that classic ocean liner look. Most cruise ships are butt-ugly. Anyway... Aside for the nautical interest, the best thing about a cruise is not having to pack and unpack as you visit different places from one day to the next. It's like having a hotel room that follows you. Here's some info on two Caribbean cruises we did. I tend to be more interested in the ships than anything else...

These are pre-canned cruise ports that are literally walled off from the indigenous population. They're designed by the cruise companies to show you what they think you want to see. Not saying that's a bad thing. Just don't expect that it's going to be some sort of cultural experience.
