Just throwing an idea out there...I spent the night in Beckley, WV a few years ago and that is a really cool area. Should be within reasonable range for MD or VA NSXers.
I happened to be on the Tail of the Dragon a few weeks ago, as my sister was living right near there. In the Tail of the Dragon area, I would recommend the Phillips Motel in Robbinsville, which is an old-fashioned motor court kind of motel which was friendly and low key and welcomes car clubs. They had a "Welcome Miatas at the Gap" banner strung outside when I was there. Has a small, friendly courtyard type of area which would be good for shooting the breeze and having a coupla beers in the evening. Very close to the Dragon also.
