Sleep In Dulles Airport (IAD)

I slept there the night of November 19th, 2015. It was nice. All bathrooms are open and clean. A coffee place was open. No staff came to harass. Some bench sofas did not have arm rests so I slept comfortably. The lights went dim if I didn't move for few minutes. TV with news and sports were on all night so I could watch when bored. WiFi was on 24/7. Ed
