Excellent experience from start to finish. The web page is super easy to use and pay for the parking...the hotel was friendly and knew exactly what to do and then the hotel shuttle waited a couple minutes while I parked my car and hitched a ride to the airport. On the return trip - the front desk let me know where to meet the shuttle and made it back to the hotel in less than 10 minutes from the Airport...and in DC that is an amazing feat. Thanks for the great experience....I will be using Book2Park again!!!!
