We camp at Holiday Shores Campground and Resort In Wisconsin Dells, Wisconsin. They have cart rentals, parts and sales of used/newer carts. We love to cart there but they only allow electric. There are off site trails nearby for gas carts that love to get crazy. Other amenities include the pretty much untouched Wisconsin River for boating, fishing and relaxing on the beaches. You can camp in a tent or bring your million dollar diesel pusher. They also rent park models to accommodate large groups. I could go on and on. Here's a link.
