Kinda had that happen to us last week at a C2C membership campground. People pulled in thursday for the weekend, set up but did not stay that night. Friday everybody decended upon the camp site with Kayaks and kids and the protable fire pit and commenced to spread out to every inch of their site...nearly right up against the side of my trailer. Turns out they were fairly respectful but still had their fun so I can't deny them that. Go with the flow as most of that type of camper are weekend warriors and will be headed home on Sunday anyway. I'm fairly easy going when that happens unless things get really out of hand. Only had that happen once and I left...easy fix.
