We found the parking experience at the Hyatt Regency Reston, near Washington Dulles International Airport, to be very convenient, great value, and easy to find. The ability to park our car in a covered and secure lot was also a great plus. The shuttles, both leaving and returning, were clean, quick and on-time, driven by friendly professional drivers. The assistance at the hotel front desk was top notch and the ease to book the space made it a no brainer. It was also a snap to text for a shuttle onnreturn. All at a daily rate well below the cost of the airport long term economy lot! The only �negative� would be the frequency of the shuttle runs: once an hour. We didn�t have to wait very long on either end, but you could conceivably have a hour wait after a long flight if you happen to arrive at the shuttle waiting area just a minute or two after the hour. Overall, a very good experience and one we�ll use again and recommend to friends and family.
