Travel to O'Brien Stadium
University of Illinois Willard Airport (CMI) is 63 km (39 mi) away. Build a real transfer window into the arrival day and do not schedule anything important before midday.
At 1.8 km (1.1 mi) from the city centre it is a short ride from downtown hotels rather than a walk.
Charleston has 4 venues mapped in total and a population of 17,361. The Charleston guide covers the airport, the local time zone and what else is bookable nearby.
What fits in this room
A room this size is a plenary and nothing else. Keynotes, awards and general sessions work; the breakouts, the exhibition and the catering all have to happen somewhere else, so the venue is really the anchor of a campus rather than the whole event.
- award ceremonies
A stage, a bowl of seats and a control room already in place.
- festivals
An audience of 10,000 is festival scale, not conference scale.
- company all-hands
One room, everybody in it, nobody watching on a screen in an overflow space.
