It was an hour and half less than the advertised 12-hour sightseeing tour. More than made up by Walter, our "transportation and tour specialist", who was very entertaining and knowledgeable guide. We were picked up at our hotel at the designated time of 6:20 by a shuttle bus driver who was not very friendly. Picked up more passengers and was dropped off at the main bus station. We were given breakfast boxes containing cookies, banana, and water or orange juice. Waited for more passengers and got late start. Then Walter took over, he made us laugh most of the time with his wit and humor and extensive knowledge of Las Vegas and its suburbs. We dropped by the Hoover Dam on our way to Grand Canyon. Walter gave us directions on our itinerary to tour the Grand Canyon tour and suggested total time to spend on each station to tour. He made sure we understood the directions and emphasized to observe the time. Walter was very kind and particularly accommodating to a couple who had a minor disability. I wish we were given more than the 3 hours allotted to tour Grand Canyon. On the way back, Walter gave us tips on how to recoup the cost of our trip, and how to enjoy fine dining in Las Vegas at a less cost. He dropped off all passengers to our respective hotels. Except for the limited time in Grand Canyon, overall, it was still a very good trip. I recommend Sweet Tours and Walter.
