Great tour of the Grand canyon, Hoover dam, and route 66. Guides are excellent. Tracy was very informative and easy to talk to. But I must warn you the south rim is about 4.5 hours away from Las Vegas. And the Ford Econoline Vans are not comfortable at all. That's about 9 hours in a van. Serious upgrades required for transportation. They do serve breakfast, and lunch, and unlimited water on the trip. It is very affordable for what they offer but man the transport needs updating badly. Also if weather is not good at the Grand canyon later in the day, they should adjust the trip to go to the Grand canyon first, then on the way back go to Hoover dam and route 66. No one wants to drive 4.5 hrs to see the canyon for an hour before it rains.
