Mark and Stoney took us on an entertaining, sight-seeing adventure to various beautiful spots around the Grand Canyon. They focused on less-crowded areas with stunning views. They shared quite a bit about Grand Canyon history and made us laugh. The Hummers are safari-style, seating 12 people. They have car seats for little ones. It was chilly, so the Hummer was enclosed, but we could see all the scenery and made numerous stops to all pile out and take in the sites. A great way to orient yourself early into your trip to the Grand Canyon.
