I think the real question is one of consideration of others, No matter what you rent for was personal use is it right and allowable for complete strangers to encroach without asking permission. Does it really matter what the renter has planned for that area. Would you share a motel room, time share, or anything else with complete strangers. What is the difference between a motel and a campsite. I welcome most snybody into my campsite but I do the inviting. Do we as a society expect this type of rude behavior as socially acceptable?
