Hershey Park? I am not surprised by that at all. Its not just a park, its a destination. You can spend a few days vacation there. You have the park, the factory, camping, cabins, the Hershey Hotel (from what I hear is not cheap). You also have Lancaster and Stasburg, which are other popular towns within 30 min drive from the park. What does Great Adventure have in comparison. I also think Hershey is a way nicer park as well
