I took part in the three-day tour departing from Las Vegas, and I can say that I couldn't have chosen better. On the morning of departure I saw large buses with dozens of people leaving, and when I saw our small van (ten people!) I was very happy. Small "penalty" of having to organize the storage of the trolleys for the three days, as the space is limited, only small bags are allowed. But it's definitely worth it! The tour is wonderful, you visit the most interesting parks reachable from Las Vegas, and despite the fact that the kilometers covered are many, you don't feel the weight of it. Our guide Jonny stopped to refresh us every hour and a half, he discreetly entertained us with excellent music and interesting explanations on the places visited, he was professional, discreet but always present and available, perfect I would say! The hotel where we stayed was very comfortable and clean. Top marks for the organization and leadership! Last note, the luck of having met truly special travel companions. Highly recommended!
