The Hyatt Arlington is in Rosslyn, a neighborhood just across the river from the Lincoln Monument. While it's not walking distance to the wedding location, it's a short Metro train trip (less than 10 minutes and about $3). As part of the wedding group rate, rooms on Friday and Saturday night are $89 per night for a king-size bed and $99 per night for two double beds before taxes. (Add about $10 per night for taxes.)

Hundreds of hotels are in the area. The wedding is within walking distance of both Metro Center and Gallery Place/Chinatown metro stations. Every color of train line goes through one of those two stations, so any hotel near a Metro station in Virginia, D.C. or Maryland is an easy commute.
