Fine KOA, but watch out for fees
Unlike the campgrounds at other cedar fair properties, the Kings Dominion Campground is managed by KOA rather than the park itself. It's a perfectly fine park, friendly staff, well kept, good amenities, and there's a free shuttle running to and from the park. My only complaint and the reason this is only 4 stars is because they'll charge you an extra $20 for early check in, which is required if you want to go to the theme park at opening. Otherwise check in is at 2pm, well after the park gates are open and the lines have gotten longer.
