Great tour operated by Airbridge company, you will be amaized by the grandeur of the Grand Canyon. Tour is very well organized and the tour guide/driver told a lot of interesting facts on a way there and back. The tour from Las Vegas takes about 4 hours driving to the canyon (but I didn't find it tiring). The driver takes you to the Grand Canyon travel centre, from where you will be given 3-4 hours of free time. In this time you will need to take shuttle buses to lookout points and a farm (7-10 minute ride). There are two major lookouts on the West Rim: Eagle point and Guano point. Skywalk is situated at Eagle pont, and truly I find that Skywalk was a waste of money as you are not allowed to take your camera with you plus there will be photographers who make people do funny poses even lie down on the floor and you can buy their pictures. I would rather recommend going to Guano point (my favorite for views) where you can wonder on you own and will be able to see 360 degrees panoram of the canyon - magnificent.
