At RIO Washingtonian, we meet outside on the turf space that is lake-front near the Washingtonian Paddleboats entry. You can use 9811 Washingtonian Blvd, Gaithersburg, MD 20878 as an address, and the easiest entry way is near the AMC Theaters. Parking is available in several different areas, and the turf is a short walk from the garage directly above Muse Paintbar.
