We visit PGA often and are trying to figure out where they are going to put Survivor.
From the few construction photos available, it looks to me like PGA is going to plop it where Centrifuge is. (They'd have to remove it.) In one photo you can see a cone-shaped buliding: Kid's Stuff, and the gondola ride: (Delta Flyer). It's one of the few places with a clump of trees that will fit in with the jungle theme. And it's near the water park.
On a larger note, I wish Great America would add more "real" coasters. In the past few years they have been concentrating on Boomerang Bay, their water park. Sadly, their thrill rides have suffered. (Top Gun and Invertigo are awesome, though!)
On a positive note, PGA has been making a strong effort to make the park more "Family Friendly". Going to PGA is always a much more enjoyable experience than any Six Flags park provides: i.e. Marine World.
So I guess we are mixed up. We like the family atmosphere goal of PGA, but want more thrill rides. Which park is best at achieving that balance?
