Where to camp near Hershey PA?

Hi There, I am looking to go camping at the end of June near Hershey PA. I have never camped out in the area and would like to know what is a good camp ground. I will admit to enjoying a toilet and shower, but do not need a pool and daily scheduled activities (there will be no children). If you have any suggestions, I would greatly apreciate them!!! Thank you all!!!
