I think that's crazy. We usually leave a campground earlier than the check out time. So, does that mean they are going to give us $10 back? see how crazy that sounds? As far as cleaning, I have seen very little of that. Most places we go, I usually am picking up cigarette butts and disposing of them. I don't think I have ever seen anyone leave a camp slot with trash and garbage on it. Just the cigarette butts now and again. If a camp ground is cheap about the early fee, they are cheap about everything else too. Not for me.
