I love Book2Park. It makes the experience of flying out of Reagan National Airport so much easier and less costly. The hotel is on the way from Fredericksburg, VA for me, and parking is fairly easy (especially now). The shuttle is convenient going to the airport. The drivers are very friendly. While I have given a 5 for excellent, I seem to have bad luck when arriving at National since the shuttles come at the quarter hour and my flights seem to arrive just after the shuttles leave so I am stuck waiting for at least 29 minutes every time in the worst possible weather. Not the fault of the hotel by any means.
