We visited on the strength of published guidebooks and the UNESCO World Heritage site status. This is indeed an interesting, unusual attraction. The high point - the multi-story pueblo buildings are built and maintained (using subsidies from UNESCO) in the exact same way they were centuries ago. Some of the one-story buildings are mostly authentic, but might have (for example) tar-paper roofs to reduce maintenance. None of the buildings have electricity or running water.
Quite a few of the buildings have jewelry, craft, or food shops in them, usually with the maker of the goods behind the table. These locations also do not have electricity or running water, but skylights provide enough light to examine what's for sale. There's a small river running through the adobe village, with sturdy bridges across it. However, the bridges and the embankment are not fenced, so you'll have to watch your smaller children carefully. It can be dusty, sunny, and windy here.
This was the most worthwhile "Pueblo" visit we made in northern New Mexico. But the price of authenticity was a hint of squalor. I don't mean to be unfair to the decision of these tribal people to maintain a living museum of their historical way of life. But you might feel awkward if you were to imagine an Appalachian "holler" where a decision was made to keep electricity and plumbing out, and have people live there full-time, while giving dulcimer concerts and selling handmade goods. Please don't let me talk you out of visiting - this project needs your money. I just want to give the whole picture.
The optional guided tour was informative and good. The guides work only for tips, so I gave ours $5. Her description of her own life was helpful, having been given a choice when she became a teenager to stay in the historic pueblo, or move to a modern tribal area. She also gave a detailed description of the Federal confiscation of their vast tribal lands, and the restoration to them of the most important, sacred Blue Lake section by Ronald Regan.
Besides admission, we also paid to park and for a camera permit tag. We were there on a regular kind of day, so there were no crowds, no outside vendors, and no performances. We were free to walk around without an escort. But we were told (quite reasonably) not to walk into open doorways that did not have an invitation sign. They are private residences.
