There is literally a station 100 m from the terminal at DCA.

The Silver Line will be open to IAD on Tuesday (15th) though I don't know if there is a bus from the stop to Udvar-Hazy, but as I recall the parking is on the airport area for those that drive. Google maps shows there is a bus that takes 16 minutes between the two. This would be the least expensive way to get there. If you are leaving on Monday there is presently a bus from the end of the silver line to IAD as well but all this is on Google maps.

There will be a bus from the airport to Udvar-Hazy, Fairfax Connector 983, but the new bus routes don't update until Wednesday. While the train opens on Tuesday, there's going to be a lot of stupid ceremonies and ribbon cuttings, etc. Don't show up at one of the new terminals at 7 am on Tuesday and expect to be able to commute.
