Booked parking for 16 days at the Hyatt Regency Reston. Instructions on the receipt was very clear for what to do before and after. Directions to the hotel was provided and so was the hotel's contact information. Did not have to interact with the hotel attendant until the day of pick up. Shuttle picked up at the airport on the hour and the driver explained that customers using book2park would need to proceed to the front desk. Went to front desk and quickly received a garage card to exit after showing the clerk my receipt, and just like that we were on our way. Parking could not have been easier along with travel to/from the airport. Will certainly use book2park for parking on all my travels.
