Information on all the travel options can be found here: http://www3.hilton.com/en/hotels/virginia/hilton-arlington-DCAVAHF/maps-directions/index.html. The hotel link page also features information about likely taxi and other transportation costs.
The closest airport is the Ronald Reagan Washington National Airport (6 miles from the hotel). Another typical option for a traveler to the D.C. area is the Dulles International Airport (26 miles from the hotel). The latter is likely to feature more international flights. The Baltimore (BWI) airport is also an option, but a bit farther away (38 miles).
Conference attendees should also note that the hotel is located on top of the Ballston Metro Stop. You can find more information about the metro system here: http://www.wmata.com/.
Another option, besides a taxi, is an airport shuttle. There are several companies that provide this kind of service. The EHA does not endorse any in particular—we urge you to look for them online.
Self-parking at the hotel is $17 per day for conference attendees.
