Etiquette in Camping

As a 'first timer' trailer owner, I reserved an rv site at a resort for a month. Spaces were tight--the next person's site began about as far as my awning went. I was right on a lake, and folks didn't think twice about walking along the lake's edge to get back and forth to friends'/relatives campsites. This meant some of them literally stepped over my feet while I was sitting in a lawn chair at lake's edge! My picnic table was nearby, and the neighbors' kids crawled over my table to get past. I finally set up floaties with bungee cords in the way. One woman pushed me aside to go past. I complained to the camp host, and when he told them they had to go on the road, they got mad at me! I overheard them talking to each other. I was therefore nervous to leave my trailer and go in to town for a couple of days for fear they've sabotage it. This next summer I'm staying at a resort where there's no one on one side of me and the other neighbor is further away. I guess campsite etiquette is almost a thing of the past.
