From the handsome approach to our hotel to the gracious lobby, from the spectacular ballrooms to the tranquil outdoor terrace, the Westfields Marriott Washington Dulles Hotel is the epitome of elegance. Our 9,170 sq ft Grand Dominion ballroom features the finest architectural detailing, luxurious lighting, and beautiful wall coverings. The outdoor terrace is equally breathtaking, with its stately red brick and stunning views of the hotel grounds. As you move from room to sumptuous room, you will see how our spaces have been crafted to not only please the eye, but also create a remarkable and truly transporting ambiance.
