We hadn't done much research in this area and hadn't planned where to go so we decided to "glamp" at the KOA.  For a KOA this was pretty nice. Restrooms were clean. Lots of activities for children.  It was expensive for close together sites and only electric and water hookups.  We did have a nice shade tree however and were able to run our A/C.  The proximity to Dinosaur National Monument was the reason we stayed 2 nights.  We explored the Utah part of the Monument (where the dinosaurs are) and thoroughly enjoyed seeing the quarry, petroglyphs and cabin.
