Various sources.
- There was a news article about attendance a while ago, and Great Adventure was the highest ranked Six Flags park. Those stats came directly from an Amusement Business article.
- The ride park, the animal safari, and the water park take up over 1000 acres combined, easily the biggest in the chain (though SFWoA isn't too far behind). Like I said, though, a huge chunk of that is the safari park. I think you can find that info on the park's website.
- I don't have an exact place to point you to for number of rides, but I know that I read that many times on these boards and others. Anyone know if that is not right? I know they added a ton of flats a couple of years ago.
- And number of coasters, obviously, comes from the fact that MM will have the world record when X is finished.
