How attendees reach it
5 km (3.1 mi) to Ronald Reagan Washington National Airport (DCA). At that distance the transfer is not a planning problem, which is rarer than it sounds.
Being 1.4 km (0.9 mi) from the middle of Washington means attendees can walk from their hotel, which removes the single most complained-about line in most event budgets.
Washington has 128 venues mapped in total and a population of 702,250. The Washington guide covers the airport, the local time zone and what else is bookable nearby.
Programming it
This is a room for a workshop, a chapter meeting, a training day or one track of a larger programme. Anything with an exhibition attached needs a second space.
- networking mixers
An independent space with its own character, which a mixer benefits from more than a conference does.
- fundraisers and galas
A room with a personality is worth more at a gala than square footage is.
