We stayed at Sundance also, and it was very fine. They are running full so call soon. While there make sure you visit Anasazi Heritage Center. We enjoyed it a lot. Also look into Hovenweep. We couldn't make the walk. If you can't get in, you can take the drive back from Durango. We stayed at Aspen Rose as did the rally. If in Durango, lunch or dinner at Ken and Sues is a must. Great food at an extremely reasonable price. If in Durango and you do the train, we would do train one way and bus the other. Sit on the right going up and left coming back. The park has dog walking service.
