I got taken when I was about 7, then once again when I was 13. I remember thinking the whole thing was pretty warped and bizarre to say the least the second time round, and feeling desperate to explore actual places in the world rather than being route-marched around a surreal succession of queues that had been built on top of a Florida swamp.
So, would you take your kids there if/when you're parents? I guess on one hand kids like to have fun and go on rides and the like. But on the other hand you'd actually have to spend your own time and money doing it, when you could be doing something much more culturally enriching. But then again: ace rollercoasters.
