We stayed here through Thousand Trails, so I don't know if it's normal operating procedure, but the sites were first come first serve. We were coming from a few hours away on a Friday afternoon, so we were sent to the left when we arrived. It wasn't clearly marked, so we got a little stuck and scraped up our rig. For better or worse, there was zero light in the area we were in, so it was hard to back into our spot. We ended up in an area where it seemed everyone was seasonal and not actually at the site, so it was very quiet. 

There were wifi repeaters all over the place (though it wasn't free) and once it was light out, we took a walk around the grounds. It's very pretty and the other side of the campground (to the right when you come in) was much more busy. That's where the playground was. We hit Warren Dunes State Park (20-25 minutes away?) and found a farm to do the pumpkin & corn maze stuff that happens in the rural Midwest in Autumn. The Bear Cave was closed and they weren't doing tours when we went, but we found it and could peak in. Looks like it would be cool to check out. No clue how big it is though.

I would stay here again, but would also consider alternatives when I go back to the area.
