Located on 48 acres of Potomac River waterfront south of Washington, D.C., Gaylord National? is the centerpiece of a groundbreaking regional mixed-use development that raises the bar for leisure and business travel options near the U.S. capital. The four-star, 2,000-key hotel and 825,000-square-foot convention center count among the region's largest hospitality properties. Housed under a dramatic 17-story, glass-arch atrium are lush gardens, waterscapes and guest amenities including restaurants, bars, retail and a Canyon Ranch spa. A large outdoor amphitheater and marina offer additional diversions, as well as a water taxi service to downtown D.C.
