Getting there

Allow half an hour each way to Ronald Reagan Washington National Airport (DCA), 11 km (6.8 mi) away, and rather more if your first session starts during the morning peak.

6.2 km (3.9 mi) from the centre puts this outside comfortable walking range of any hotel district, so the shuttle is part of the event rather than an extra.

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.

Formats this suits

4,200 is enough for a whole programme in a single room, which removes the hardest logistics problem an event has. Ask what the room looks like empty — the seated figure and the usable one are rarely the same.

  • 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.

  • community meetings

    Room for 4,200 covers most community and member meetings.
