I stayed at the campground with my older kids.  It's a very large campground and spread out, which is great for privacy.  We LOVED our campsite, as it was very private and shaded, although a little bit of a walk to the restrooms.  

I would highly recommend bring bikes if you can.  There is a nice bike trail.  We didn't hit the hiking trails, but they were available.  It was very quiet.  We normally camp at Caesar Creek, and we were a little disappointed that there was not a camping beach available, since that's one of our favorite things to do.  The beach and water recreation area are a long drive away, which made it more trouble than it was worth.

If you're looking for quiet, beautiful setting, this is the place.  If you have a boat, it's nice large lake.  If you're looking to be entertained, this may not be the spot for you.
