I am, however, flying out of IAD on Tuesday (only for one night) and I'll park at Herndon-Monroe and share my experiences in this thread!
Did this work? I face a 16 day parking problem next week, driving to IAD from central VA. Is taking a cab from IAD to Herndon-Monroe to retrieve the car an option?
