We had a great time on this tour. Just know the day starts early. Our guide Diane, seemingly had knowledge on EVERYTHING in the area on the drive, from Phoenix all the way to the Canyon, Route 66, and back. Diane was entertaining, wonderful, humorous, and very flexible, as she allowed us to basically pace our own time in the park, and not be forced to see things in a certain order. The Grand Canyon was magnificent as ever, and the pics dont even do it justice. Prepare for the temperature to be 20 degrees colder, if you're coming up from the Phoenix area. I wish we would've had a little more time in William's to see the shops along Route 66, but besides that, I have no complaints.
