This was a great alternative to ordinary Dulles airport parking! It was much cheaper than the airport lots (half the price!) and yet the service was just as good if not better. Our lot was a DoubleTree Hotel and the driver treated us like VIPs- handling our luggage for us and very friendly and professional. The shuttles run on the same schedule as the airport lots, so you'd be crazy not to use this service. You've got a Permanent customer in us!
