National Air and Space Museum
Start with the marquee day while everyone’s fresh. The National Air and Space Museum on the Mall is mid-way through a multi-year renovation, with about half its galleries open right now — new spaces, a renovated planetarium, the 1903 Wright Flyer, and a touchable piece of the Moon. Kids around 6 and 9 are exactly the right age for "real spaceship, right there." Reserve free timed-entry passes in advance, and check the IMAX schedule if you want one big-ticket extra.
