JUNE 2016 UPDATE - We had the same experience with the same lady and we were not happy with our site at all and we were going to be here for 2 weeks while working at Sam's this visit. We found a perfect site for us and luckily when we went to the office, she was not there and the man took care of us very well. We stayed in the back off the asphalt and off the gravel on a concrete slab which was flat. It seemed much cooler since there was grass and trees that shaded our site without hanging over us. We were happy campers!
We paid $40 per night for a water, electric and sewer site on gravel (very flat concrete the second visit). There WiFi was exceptional most of the time, occasionally we had to reboot to get better signal but overall it worked great.
This is a State Fair park that has no extras, only restrooms that you need to leave a $20 deposit for and a laundry room with just a few washer and dryers.
The neighborhood was not bad and we always felt safe, especially with overnight security at all times.
