We used Econopark Express at BWI for a week. I will park there again in the future. It was convenient, no airport traffic or over crowded shuttle to deal with. The Econopark shuttle driver picked us up and dropped is off right at our car and put our heavy bags on and off. After we landed I was going to call to be picked up and the driver pulled right up for us. I got a coupon on the internet and it was less expensive then parking at the airport.
