Thanks for the link bhatnasx. I don't have to use BWI much (thankfully, as I live awfully far away from it) but Airport Fast Park runs a top-notch operation. It's not only the cheapest parking facility at BWI, it's the most convenient. Every time I've parked there, a shuttle van follows me to my space as soon as I pull my car into the lot...and we arrive at the terminal in about 5 minutes.
