DC with Kids

I recently (last week of October) took the kids, ages 5, 7, 9, and 11 to DC for a sightseeing trip.  We loved it!! Stayed at the Embassy Suites on 22nd Street -- a great choice!  The reason I say that is the full breakfasts and the manager's special -- my kids loved the free sodas/nachos and it really curbed the appetites for supper.  We ate lightly.  This cannot be beat.  The sights:  Our favorites were the Capitol Tour (contact your congressman ahead of time), you will get in.  The Trolley (2 days) was fun- the zoo was great (took a cab there).  Loved the museums.  Keep in mind, generally, all the sights are free - just get yourselves there, get a value room and enjoy!!!
