Found this van-ride tour of the South Rim of the Grand Canyon icw our stay atthe Best Western Plus of Williams. For $149/per person we had a full day van tour of the south rim overviews, making 5 or 6 stops. Park entry ($25/vehicle) and lunch were included. Our guide, Tim, was a young ASU grad who had worked previously in the Grand Canyon as an Americorps volunteer so he had solid knowledge of the history, geology and attractions to serve as a competent guide. We had 11 people in a 15-pax van, so not too crowded in. We departed the hotel at 0830 and were in the park before 1000. The tour lasted until around 5pm. Lunch was included - down at the Cameron Trading Post - which was a 25 mile drive out the east gate. This took some time away from the tour, but meant that we got to visit the Navaho Nation, and is a chance to shop for authenic souveniers. Overall, an enjoyable day and a good value - especially if you are not staying in the Canyon Village. saved us the 100+ miles of driving.
