It's a really nice KOA. Easy in and out and close to both King's Dominion and the state fairgrounds. It does have a shuttle that will take you to the park and back for free that runs all day and into the evening. They have a ton of spaces but they do get full on busy weekends. The pull through spots are big and flat except for the one double spot. For some reason that one is on a slope. There's a truck stop across the road from King's Dominion, although there are much nicer ones just up the I95 in Ruther Glen. Down the 95 is Ashland where there are a number of RV dealers and a Walmart that carries RV supplies.
You can park at King's Dominion, but they'll put you by the buses. You won't want to put your slides out there.
