hey Ron. Me and G have went to the N and S rims but refuse to to go to the skywalk. The price is outrageous! Also you can't take any pics on it. I don't know of ANY discounts because it is so new and the Tribe is being crazy about the prices. If you have never been to either side of the canyon, I would suggest driving to the South rim. They have tons of shuttles to take you all around it. We even drove out to Williams Az and rode the train to the Canyon. It was a big Diesel on the trip in, but on the trip back we got to ride a Steamer train. It was very cool. Email if you want some more info on either side.
