There's tons to do to prepare for the holidays -- and having fun should be part of the mix. Take a break from all the shopping and decorating, and relax as the soothing waves of the Potomac gently rock your National Ferry Corporation luxury sightseeing vessel on a Holiday Harbor Lights Cruise. Enjoy the twinkling lights of the city from the climate-controlled vessel as it navigates the harbor, looking away only to sip a cocktail available for purchase or chat with your companions. Festive decor and holiday music further set the vibe, so that once the 90-minute sail returns to dock you'll be fully ready for the flurry of the holiday season.
