Stayed here for 3 nights in July of 2019. Convenient location for the hikes we were doing and not too far from the west or east entrance to the park. Arguably the cleanest vault toilet I have ever seen. The campground host took pride in maintaining the place. Went in Mid-July, the campground was probably at 2/3rds capacity and we didn't have any neighbors on either side which was very nice. Warm during the day and cool at nights. 

10-sleep is just a short drive away for gas and food and most importantly a spectacularly Wyoming brewery.
