Dinner Dance on the Potomac River

For many, the dinner dance aboard the Spirit of Washington is the highlight of the DC trip!  After a full day of sightseeing, we return to the hotel in mid afternoon to give everyone an opportunity to get dressed in their finery.

We will arrive dockside at about 6:30, at which time we will board our awaiting ship for three hours of food and fun.
