If that's the KOA with the lodge, it is 10's all around. We stayed at the KOA in Rapid CIty as there were many places we wanted to visit in the area and it was centrally located - Badlands, Wall SD, Sturgis, mammoth site S of Rushmore, etc. You will also not be too far from Devils Tower in Sundance, WY. KOA there is nice too.
