Typical KOA: large overpriced campground, nice pool, friendly staff, sites close together, older campground needing some maintenance. Close to Six Flags.
If you do not need a pool, this is a great place to stay when visiting the St. Louis area. Some sites are very close together. The office is normally closed. If you need to talk to the someone, you need to call them.
Friendly staff, helpful, small sites, dated facilities, easy access. Parked on the site next to us was an empty 5th wheel (I think it was a rental). What may be classified as a pull through, exited directly to the street. Overpriced for the facility.
Nice RV park: clean, large site, level, easy access, small trees. Trains, Trains, Trains. We stayed for a week while visiting area. Would stay here again.
