Interesting - I'll have to compare rates on this the next time I decide to overnight up there.
FWIW, I've stayed in Goulding's before and it's really a nice relaxing little place. I brought some extended family along for a tour, and we actually reserved a 3-bedroom house they have available. It sits high up and has nice views, was very reasonably priced, and perfect for a larger group of people.
For the points ******, there's a Hampton Inn in Kayenta.
