Scam Alert: AWWA is aware of multiple unauthorized organizations contacting exhibitors and attendees to solicit hotel rooms. Reservations made through these unauthorized solicitors cannot be guaranteed by AWWA and could result in hidden charges, unusual restrictions, incorrect hotel placement, or nonexistent reservations. Connections Housing is the only official housing company approved by AWWA. All other solicitors should be considered fraudulent.
Note: Any reservation cancelled after April 24, 2026, will incur a $50 fee, in addition to the hotel’s cancellation policy.

Getting to Washington D.C.

By Plane: The Washington, D.C. area is served by three major airports: Ronald Reagan Washington National Airport (DCA), Washington Dulles International Airport (IAD), and Baltimore/Washington International Thurgood Marshall Airport (BWI). DCA is the closest to the city, while IAD handles many international flights. BWI also offers access to the city via train and other transport options. All three have various public transit and ride-sharing options to help travelers reach their destinations.

By Train: If train travel is more your style, Amtrak has several rail lines that serve D.C.’s Union Station and is connected to the D.C. Metro on the Red Line. Union Station is in the heart of downtown and a short walk or bus ride away from the convention center and conference hotels.
