We took the Grand Canyon south rim tour and it was wonderful. Our guide Barry arrived right on time and made the trip delightful. He struck the right balance of conversation and down time as we made our way first to Hoover Dam, then to Route 66 and finally to the Grand Canyon. He helped us choose the right hike length for our group and then took great care of us on the way back to our hotel. Also picnic breakfasts and lunches were just the right size and accommodated our son's need for gluten free meals.
