I've camped here many times and have always liked it here. It is in the center of all the attractions. Can be a little noisy with the crowds and RVs. 

We decided to come here one year in early September last year and it was still pretty hot even at night. We were tent camping and it was difficulty to sleep due to the heat. We did a walk in site and there were plenty openings. In the middle of the night there was a sudden dust storm so we had to pack up the tent and equipment quickly. There were 2 or 3 other tent campers and they also packed up. We ended up just sleeping in the car that night, lol. The RVers were fine. 

Other than that it's a great campsite. Haha. Close to the visitor center as well. Clean restrooms.
