I took the Peak 1 shuttle from Denver Airport to the Vail Transportation Center, and found it to be a very easy experience. The pickup location was conveniently located just outside the baggage claim area. The driver arrived right on time, and we had a smooth ride to Vail in a nice, comfortable van. Our driver, Jason, was very helpful with advice on things to do in the Vail area, as well as restaurant recommendations. The ride included free WiFi and water bottles in the van, which both came in very handy. I will be travelling back in a couple of days, and despite my original plans to rent a car for the return trip, I decided to go for the convenience of the shuttle again instead. Renting a car would have involved a lengthy bus ride to the Eagle-Vail airport for pick-up, and then the return at the airport. Getting direct service by shuttle just seems easier.
