I'm considering taking a bus from NYC to DC on Thanksgiving Day that stops by the Bethesda Red Line station.
The idea is that I'd have to take the Red Line from Union Station to my Metro Center hotel anyway with other bus lines, and this both shaves half an hour off of the sitting-on-a-bus time and avoids in-city traffic. I have a strong personal preference for sitting on trains over buses. Amtrak, sadly, is sold out.
Over on the NYC board someone tells me that the Red Line is a mess on weekends and holidays. Will they be running sufficient trains from Bethesda on Thanksgiving, d'you think?
