Have you been on a world cruise?

world cruise
Time T asked:

i really want to go on a world cruise, it’s like my dream. I’m only 15 but i’ve decided that is my goal and i’m going to start saving right now. They’re really expensive since they’re between 95 to 120 days longs. Has anyone been on one? How’d you like it, was it worth it, did you get bored?
