I was totally blown away with Hershey on Saturday (June 9th). I'm in the middle of writing a trip report, but it ranks up there as one of my favorite parks now. I've never been one to like wooden coasters, but I loved all of theirs - especially Lightning Racer. Although the park looked and felt like it was going to burst at the seams from people, the queues were relatively non-existent.
Chocolate World was just eh. I wish they actually had the REAL factory tour still.
