A friend and I took this tour while in Las Vegas for a convention in June. It was easy booking through Trip Advisor. I was actually able to call and speak to Sweet Tours in advance and actually got a real person on the phone! Linda was wonderful to speak with and did exactly as she said she was going to do, even though I booked through Trip Advisor and not directly through them. The directions given to me on where to meet the tour guide for pick up, was very helpful, as we were staying at the MGM grand, and may not have found that exact door otherwise. Bil C was our tour guide, and he was wonderful! He was so helpful and informative! He was a wealth of knowledge on the area, as well as the information about the Dam. He was very clear on pick up times, and how long we would be at each location throughout the day. He made sure that we always had fresh, cold water to drink, and reinforced hydration to everyone on the tour. The water was a wonderful addition to the tour that I really took advantage of. Bil was very professional, and punctual! Pick up from our hotel went very smoothly. We were a full tour, and everyone on the tour was pleasant to each other. The tour lasted exactly as long as it said, from pick up to drop off. It was a full day of touring, and worth every dime we paid for it! If ever out that way again, I would like to do a tour of the Grand Canyon that is offered by this company. The only thing I regret, is not having thought to bring tip money to give Bil! Next time I will make sure to remember! Take this tour, you will not be disappointed!
