I live near Lorton in Northern Va. I do not recall any hotels other than
the Comfort Inn near the Auto Train station. I would stay in the Woodbridge
area if it were for a weekend departure and you could probably save some
money. On weekdays the traffic is terrible here, rush "hour" starts around
5am and ends around 10am, and in the Springfield area there is alot of
construction on I-95. So on weekdays the only sane choice is to stay in
Lorton at the Comfort. There is not much there except the hotel, a gas station,
and the hotel so don't expect any restaurants within walking distance.
