I am leaving on a mission trip this September and I am looking for a hotel near Dulles that allows you to keep your car there for free or almost free while you are gone. The hotel would also have to have a shuttle or reliable taxi service in the early morning hours (3 am). I did this once in Philadelphia and it was great.
Otherwise, I would have to drive several hours to get to Dulles by 3:30 a.m. so I would prefer to stay in a hotel at the airport and keep my car there.
Does anyone know of any decent options close to the airport? Thanks.
