We're doing some planning for the great Darwin clan expedition to the DC area in late March, and since I have never been to the Capitol before (and MrsDarwin has not been there in many years) we're thinking this is our chance to get some Visiting Of Sites Of Interest in.
We will probably be devoting 1-2 days to seeing things around DC itself (Lincoln memorial, Washington monument, Capitol building, etc.) Any advice on what is worth seeing and reasonable to see with four children ranging from 1.5 to 7 and a wife who is increasingly pregnant would be much appreciated.
We're also thinking of things that might be worth making one-day-trips to. Right now, the primary candidates are Gettysburg and Colonial Williamsburg, which to our Texas eyes look quite close. Anyone with experience taking a pack of small children to these places? Any advice on other places that might be worth considering within 2-3 hours drive of the DC area?
