I'm exploring some alternative commuting options (headed to DC) and am considering taking the Loudoun bus from Dulles North. I've read for years about the parking issues there, but haven't seen anything recently (and have never tried it), so am wondering if anyone can report on recent experiences. I'm specifically wondering when the lot tends to fill up these days. I would be arriving around 7am, trying to catch a 7:15am bus. I've considered picking up a bus at some of the closer locations (Brambleton, etc.), but the schedule options seem much more limited. Thanks for any insights.
