Even though we had been camping on this road trip and had our gear in the car, we elected to stay in one of the camping cabins at the Williams KOA and it was quite a treat. Even in the late summer, it can get cool in the evening, so we were thankful for the extra shelter. After dinner by the campfire ring, we went to bed and awoke the next morning to take the little Williams train into the South Rim where we hiked for a couple of miles with our 4-year-old. She did surprisingly well, and it ended being a great little short stay at the GC.
