Well, I guess I can understand the charge for friends but an adult child or other family should not be charged. I know most campgrounds, especially state parks, charge for extra people but their per night charge is around 1/3 of FW.
I guess while I am on a simi-rant.
The last time we were at FW, over Thanksgiving week We saw a motor home on a full hook up site that had a small pop up at the back of site and a tent off in the grass along with 2 cars parked along the front of the site. We were there for 5 days and they were still there with the same set up the day we pulled out. It seemed about 1/3 of the sites had 2 cars on them. The back side of the 1300 was so crowded with cars you had a hard time getting a golf cart through let alone a big rig. How do these people get away with this?
