My wife and I drove up to DC to meet a couple of old friends in for a conference and spent the night at one of the Hilton hotels. The hotel charged us only $10 for overnight parking but they would charge more if we didn't have a room.
I jokingly mentioned about the parking charge and the woman at the front desk gave us coupons for a free buffet breakfast.
nice I can stay with relatives in VA and take the train in. I like the zone taxi fees in DC
