We were very pleased with this Hilton's Book2Park service. The hotel is easy to locate, has lots of parking, great service at the lobby desk, and a dependable shuttle service. The driver was pleasant and got us to the airport quickly. Since it was very early (4:30 am) we got dropped off right at the United ticket counter which was great. Using your parking & shuttle service is a stress free way to start and end our vacation. Pick up at the airport is dependable too. We always use your Book2Park service when we fly out of Dulles Airport.
