I stayed at Harrisburg East Campground during the 2012 Hershey RV Show: Harrisburg East Campground and Storage
Rates are decent....I paid $30 per nite with 30 amp and water hookups. I just dumped the tanks when leaving, so I didn't need sewer.
Most of the sites were fairly level, although I had to jack the front of my camper up pretty high to get in level in my site.
There were some seasonal campers there, as well as at least 1 family living in their motor home, but no problems. Some sites are about 100 yds from the interstate......other than that it was quiet........of course with the interstate, you couldn't tell if you had noisy neighbors or not.
Easy to get to Hershey Park from there. I had some friends that stayed in the Lancaster area, and they had a long drive to Hershey, as well as being tied up in accident traffic for a couple of hours 1 day trying to get to the RV show.
I will stay at Harrisburg East again when I attend the Hershey RV Show next time.
