If you will look at the park reviews section of this website you will find 13 reviews of two campgrounds in Ocean City. At least one of these campgrounds, Frontiertown Family Campground, has full hookups.
Try Fort Whaley Campground.....About 10 miles west of OC. on rt 50......State and Federal Park on the Assateque Island 6 miles south of OC> on rt.611....Frontier Town Is a very busy family campground.....Ok for the family ....Peace and quiet try Fort Whaley on Route 50.....A couple of the campgrounds close in OC. are selling out to developers.....High $ property values ...Iam surprise they have lasted this long.......Jim
