If the moment moves you, paddle boats (pedal boats, really), can be rented in 2 or 4 seat versions for you to tour the Tidal Basin in the water rather than walking the path that surrounds it. Contact Tidal Basin Paddle Boats, 1501 Maine Ave, SW, Washington, DC 20024. Phone 202-479-2426 or go to www.tidalbasinpaddleboats.com
