Trip ideas besides the Crayola Factory?

Hi, I'm planning a quick spontaneous trip to PA for Memorial Day weekend. It will be me, my hubby and our 8 yr old daughter. We'd like to stop at the Crayola Factory. We went there a few yrs ago and it was nice but other than that, what can we do around that area? We prefer to stay away from Hershey park because its just too expensive. She's too old for the Please Touch museum. We want to do something low key but fun around there without going broke. Any ideas?? Thanks!
