OP here. I can clear up a few things. Yes we did receive an email with the quiet times prior to arrival. I just missed that line. Nothing was mentioned when we arrived about a group. The other rules were the usual stuff about pets, no loud music, two vehicles, four campers per site and the basics.
The campground only has about 28 sites which are not much more than a gravel parking lot. FHU and clean but all the sites are side by side in two rows.
I feel they should have warned us upon arrival. The owners were very nice and accommodating the first two days but have totally ignored us since. Like they knew what was coming.
No thoughts of calling the cops.
My post was not so much about getting a refund or just complaining about a misadventure. It was to ask what others thought of the quiet time hours being between 12:30 am and 6 am.
We are half-timers I suppose so we are off today on a new adventure. This will be in the rear view mirror soon.
'Lantley' - I agree but why have a set of rules if they will not be enforced? I would have no problem with a group. We have traveled in a group at times. My problem is with 50 people together drinking, loud until after midnight, music all day and most of the night, cars and trucks everywhere clogging up the roads and every corner of the campground.
