I absolutely love book2park! It saves so much money, and often times it saves you time! This was my first time parking at courtyard Alexandria Pentagon South. It was covered garage parking. The checkin was smooth and the shuttle was right on time. Everyone I encountered there was super nice and accommodating to getting us to and from the airport. We did stop at the metro to pick up another hotel guest, but it only took a couple minutes and we were still back to the hotel in 15 minutes. I'd park here again!
