We went at the end of September, off peak season. Instantly notice how huge this KOA was. Whole rows of the various types of sites, lots of cabins and housing as well. Lots of kids activities as well.
We stayed at a deluxe pull thru. Very nice, good space between neighbors. Overall good KOA, no issues and we had a great trip.
Things to note: It has a very large seasonal section There are train tracks in front so you will hear the train several times a day. Very little shade (consideration for summer) Close to Cedar Point
