We have noticed the few RV Resorts we stayed at didn't have the same problems.
The kids acted like our kids and were probably bettered mannered than me.
Cost of one in particular in Michigan, we consider high, at the time not haveing experienced too many Resorts.
It has a long pond that fronted all of the Sites and crew that kept them trimmed and so forth every day, and flowers and ducks and first class everything. We didn't quite fit in, with wine gatherings but every one was nice and more refined. Most earned in a year what we earned in five and that figure astonished me. Wife must have had all the shoes gold plated.
I guess price does help exclude those that don't have a purpose, in life or civility and manners. No, I'm not snooty. :)
