Not to flame or degrade anyone - BUT - Canyon de Chelly has always been one of those special places for me. We usually will spend just one night and arrive early enough to do the entire loop drive. We always have dinner in the lodge and make an effort to speak with the locals in and about the Monument. It has always made me feel as close to having a religious experience every time I go even just writing this post gives me Goosebumps so sorry it did little for you.
In the grand scheme of things it is really just a small spot on the map that is visited by few - but for Us it will always be Special - we have never spoken to anyone we have suggested to going there that did not just Love it and the people associated with it.
Sorry it did not affect you more positively, Maybe next time.
JMHO,
