Go to Hershey. Kosher food in Harrisburg 10 minutes away. Not sure how much yoou want to spend though. If you want to spend as much as you would at Herrs, Hershey is not for you, the indoor activities cost a bit more. This time of year you can get rooms for $50-$60.
About 25 minutes from the Herrs factory is Lancaster. Must be SOMETHING for you to do there. I dont mean to stereotype, but great outlet malls there if thats your thing. Shopping not your thing, ask your Rav if the Mennonite temple is something you can visit (Ive been meaning to ask mine for a long time but it has never come up as a practical question).
