The Gettysburg KOA is nice (but pricey) and we stayed there 3 times (most recent for the 150th Anniversary of the battle).
The owners are great but it is an old campground. The 50 amp service sites are newer and fine, but the 30 amp loop we were on still has low power in the heat ( Franks stage one boost was on the entire time we used air conditioning to keep voltage above 110).
Pool was small and was crowded on the weekends.
Our next visit will be to another campground for a comparison.
