Booked this on the recommendation of some friends who had done it a couple of days prior. We wound up being the only 2 on the tour this morning, so my wife and I had a lot of attention from Spencer and his dad John. Spencer assured these two 60-year olds that we would do well and he would take good care of us, and he did! After a 20-25 minute training session, we were off. Toured through downtown Vail, and then eventually worked our way up to the bike trails around the base of the mountains. Spencer and John were very attentive to make sure we were handling the Segways well. Spencer was very knowledgeable about the area, and his enthusiasm was a real treat. We were first-time Segway riders and did not have one problem. Would heartily recommend this attraction in Vail.
