I've been to it when I was really little, I think four? I remember eating a vanilla covered chocolate ice cream shaped like Mickey Mouse's head. It was all over my mouth. Then, when it got darker we watched the fireworks.
For some reason I keep thinking I went on a ride with a train that rode around a little mountain and waterfalls. Oh, and a boat ride with dinosaurs. Passing that place, I remember looking back and seeing a giant man sitting on an edge of the cave. (I might have also got my first dinosaur toy from Disney world, too, unless that was just from traveling to some places.)
I've been to the one just outside Paris. I loved it as much as my parents hated it - I'm not sure I would today, though; I don't have time for children's activities until I get some myself, and it should be close to impossible to get a decent drink.
