That bus would be hard to access from Bethesda, which is about 10 miles west of the Greenbelt metro, unless you are willing to spend almost 30 minutes on the metro to get to Gallery Place (two stops west of Union Station), and then schlep down the escalator to the Green/Yellow line platform and ride another 30 minutes to Greenbelt; then wait for the bus for another 30-35 minutes to BWI. I understand that overnight parking in the Greenbelt park/ride lot is discouraged.
