I took this tour with my family back in May. We had an absolute great time! Our bus driver, Mark, was THE BEST! He greeted us with a smile when we got on the bus (super early in the morning, might I add). We were the first group on his bus so he talked to us a bit while we waited for everyone else to join. Throughout the day, Mark would inform the bus of all different types of facts about Las Vegas and different interesting places that we would drive past. He was always cracking jokes too which kept things very entertaining.
He gave everyone enough time at each stop (even at just the bathroom stops) to sort of look around at the scenery and everything.
Once we arrived at the Grand Canyon, he provided his cell phone number, if anyone had questions, needed help finding the bus or even just sending him pictures for fun.
Mark made the trip 10 times better and I'm glad my family was lucky enough to be on his bus!
