Most successful private campgrounds are going to primarily season leases. This is the only way the campground can pay their bills. Not sure why you have a negative opinion of seasonal campers. In my campground, we generally welcome the weekenders and enjoy the park together. Weekenders always provide a certain amount of amusement as well, and occasionally problems (excessive drinking, noise, mess, wandering through other sites uninvited, etc.)
