Recently had an overnight at Dulles International airport , and had to stay at the Holiday Inn , Chantilly. It was a great hotel , clean , the staff was very welcoming , and the room was spacious and really nice. The fire alarm happened to go off at 8:30 in the morning, but the front desk had no control over that it was someone pulling the fire alarm as a joke, not funny at all. The van had picked us up ontime when we flew into IAD and was available for our departure the next day back to the airport to catch our flight. There are a vast array of Restaurants around the hotel where you can eat without spending a fortune!
