Interstate Inn RV Park is located a tenth of a mile to the east of I-95, exit 173, and behind the Interstate Inn. This campground is a good bargain for an overnight stay. 18 bucks gets you cable (and HBO) plus good fast wireless.
There are three rows of sites… get into the first or second row (the ones nearest the motel) because the last row has a pronounced slope. There is no dump at the sites, but there is a dump station. While we would think twice about staying at the motel (a little too old for our taste), the group of RVers make the campground a nice place to overnight.
