Good proximity to visitors center, a cafe, store, amphitheater and many drivable views. Also quick 2 miles out of the park to the small town of Interior for gas, etc.
Toilets were clean enough for a campsite, but PAY showers were less clean (reasonably priced for pay shower and water was hot and pressure great...I just never wanted myself or any of my belongings to touch the nasty shower curtain and you want to keep those flip flops on).
Weird layout for those with pop outs into the street as this is not a pull in place. You just parallel park on the street in a small aside like a bus stop. Many RVers had chairs in the street when their vehicle provided shade that direction. We tent camped and it seemed much more fitting for that.
That being said, the views are amazing from the camp. The night program at the amphitheater was so entertaining that we went twice! We saw buffalo, deer, mountain goats and big horn sheep while hiking or driving. There is no shade anywhere in the park unless you time the sun and some rocks in early morning or late afternoon. They do have partial covers for the picnic tables positioned in a way that blocks noon to evening sun. Also, the sturdy wood/metal covers had many hammocks hung on them- good way to relax in the afternoon heat.
We stayed 3 nights and it was enough time to drive all scenic roads, see all vistas, go to Wall Drug, and day hike all designated trails in park (backpacking you follow game trails or dried creeks and need no permit or reservation).
