Hi; My husband and I really like using your book2park facility at the Double Tree by Hilton at Dulles Airport. It is 1 hour from our house, has very friendly staff at the desk, a comfortable lobby and an easy to get to rest room to use. It has a 24 hr. a day service. The service is always dependable which I read in reviews that some of the shuttle service from other hotel parking lots are not dependable and run only certain hours. Yes, you can share this review with other customers. Thank-you for providing a good service to travelers who fly.
