The whole experience was well-planned and efficient. Booking through Viator was fast and easy. Tour operators from the company (Sweetours) contacted us to confirm details and were very helpful in providing details about where to find the pickup spot to prevent delays. They were also able to assist in changing the pickup spot to make it easier for us. We were picked up by a smaller bus and taken to the large bus that was our final mode of transportation. They were organized and were able to get everyone onto their respective busses and get on the way promptly. Our driver, Wally was very knowledgeable and described the history of Vegas, the Hoover Dam as well as the West Rim and the Hualapai Tribe. We were shown a video about the inception and creation of the glass skywalk and had one break along the way to stretch our legs and pick up lunch. Wally was truly a wonderful guide and brought us safely back to our hotels after the tour. He provided us with helpful hints about wait times and being realistic about shuttle times between the stops once we are at the rim, and he also gave us his opinion about the most efficient way to spend our time, while having the opportunity to maximize our experience. We took his advice, and were thankful we did!! The west rim was stunning and very well maintained and managed by the tribe. It was nice to have a chance to support the tribe and meeting so many lovely people and learning about not only the history of the west rim, but also about the Hualapai Tribe. We did leave an hour late because of a couple that must have gotten the time difference mixed up, but that fault cannot be placed on Sweetours or Wally - despite him mentioning the importance of punctuality and the time difference between Nevada and Arizona numerous times. Wally graciously offered to drive straight back to Vegas without making any stops to help us recoup time and dropped us back at our respective hotels. 10/10 for an excellent and efficient tour and 100/10 for Wally, our amazing guide.
