It depends on what you consider near. If you're talking within an hour...not too much. If you're talking with in three hours, there's a ton of stuff. There's also a ton of smaller parks all along the Jersey Shore. The closest more 'real' parks to SFGAd within about three hours would be Clementon (only one credit), Dorney, Sesame Place (for kids mainly), Hershey, and Knoebels.
