We just came back from three weeks' vacation and we had a pleasant experience with parking using book2park for parking at Comfort Inn & Suites Dulles Airport near IAD airport. I used google to find long term parking near IAD airport. Book2park gave me the best price for the parking lot that is close to the IAD airport. We had no problem finding the place to park our van. The shuttle bus was already waiting for us when we were unloading the van. When we came back from the airport, we called the hotel and got the direction to meet the shuttle bus. We were able to get into our van and drove away quickly. So it was a pleasant experience and I will definitely recommend it to anyone.
