Travel to The National Conference Center

17 km (11 mi) separates The National Conference Center from Washington Dulles International Airport (IAD) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.

7.3 km (4.5 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.

The published number for the venue is +1 703-729-8000.

Leesburg has 13 venues mapped in total and a population of 49,831. The Leesburg guide covers the airport, the local time zone and what else is bookable nearby.

What fits in this room

Function space is bought as a set, not as a room. Ask The National Conference Center which spaces are on the same floor and which need a lift, because a breakout two levels away loses a third of its audience at every changeover.

A worked example for The National Conference Center

Take 240 people through the door in The National Conference Center — a plausible programme at a venue of this kind in Leesburg. The first 50 activated attendees are free on every event, so only the rest are billed, and the total stops moving at 1,000 however many more turn up.

You are billed for people, not for the room, so this figure does not change if you move the event down the road. event67 has no floor-plan or booking product — the venue handles the space, the app handles the people in it.
