We took this tour with our excellent guide Alfonso on December 29th and had a brilliant time. Plenty of stops for the restroom and to stretch legs; interesting stops at Seligman and Hoover Dam; yummy lunch and informative commentary. It really was like spending a day with friends! Alfonso knew just the right spots to stop for a photo and his photography skills are outstanding! It was a long day and we were glad to return to Vegas but we would recommend this tour to anyone. The company even refunded the difference between adult and child's fare when they saw the ages of our children - without me even asking! Now that's service! Excellent day that will be one of the best memories of our trip. Thanks Alfonso and Grand Adventures for sending these Aussies home with memories to cherish for a lifetime.
