I saw book2park ad when searching for a low rate parking in Dulles Airport. At first I was skeptical and reluctant in booking because I was unsure of the location and the parking. Needless to say I tried it and it was awesome. The parking fee is cheap only 45.00 for a full week, they drop you off and pick you up from the airport. The parking is using the hotel parking and is an open space parking lot not covered but it does not matter because it was very cheap to park. I highly recommend it.
