We're spending a week in DC next month for spring break--me, wife and 2 teenage daughters. I just skimmed the thread and got some good recommendations. We're staying near the White House and won't have a car until the end of the week when we drive to Williamsburg for the last 2 nights and then back to the airport.We're planning to do the obvious things: plenty of time walking the Mall, Smithsonian museums, Holocaust/Spy/Crime&Punishment museums, Ford's Theater, Mount Vernon via the Potomac, tour of the Capitol (White House tour was cancelled due to the sequestration).A few questions:Any other less obvious must-see's/do's? Is the sequestration affecting other tourist sites?Given we won't have a car, how's the public transportation? Best places for Easter Brunch?Good places to watch NCAA tourney games?Best concert venues? I know the 9:30 Club, but what other venue calendars should I check for shows?Any other recommendations appreciated.
