If you choose to fret about spending a few dollars to visit this ancient place, DON'T GO! This is not supported by the government like Mesa Verde and many other uninhabited places.
Consider this an invitation to touch on the lifestyles of an ancient people in the modern day.
I found it to be enchanting and an opportunity to connect with some of the residents. The day was perfect enabling me to capture many wonderful photos. By all means go on the tour and tip the guide. If you're selfish and judgmental stay away!
