Travelers ❤️ these 🏨 after their flight to Washington

Hyatt Regency Dulles
All was well. Snowed in so surprised they closed the kitchen for several hours and there was NO WHERE ELSE to eat, but they were clearly short staffed. There was one bartender taking care of everything all afternoon/evening. He was a rock star!! Coffee before 6:30 would have been nice too as we had ...

Hyatt Place Herndon Dulles Airport East
Great place to stay. Close to the airport with good shuttle service. I was caught here during a snowstorm and the staff was extremely helpful. They offered shuttle service to a local shopping center. Would definitely recommend it to a friend.
