Washington DC kids attractions tips

From experience, I recommend booking early for:

- IMAX movies at the Air and Space Museum (the venerable "To Fly", and the new "Fighter Pilot"
- Trips up to the top of the Washington Monument

And, forget about getting to the new Udvar-Hazy Center site for the Air and Space Museum by public transport. Unless you are flying in or out of Dulles Airport, you will spend more time on buses and trains than at the museum itself.
