The 2020 meeting will be held at the Crystal City Marriott in Washington DC.  It is very close to Regan airport and is a one stop, 15 minute subway ride to the SFN convention center, with a subway entrance available under the hotel-- you do not even need to walk outside! 
We will have a room block for meeting attendees that will extend through the SFN meeting. More information about making reservations will be posted here.
