Capacities are the figure the venue or an encyclopaedia entry published. They are usually the seated maximum, and the same room in banquet or reception layout can differ by half. Confirm the layout you want before you plan around a number.
How people reach Mattoon
University of Illinois Willard Airport (CMI) is 62 km (39 mi) away, far enough that arrival day is genuinely a travel day and a first session before noon will lose people.
The city runs on Chicago time (America/Chicago). Schedules published in one zone and read in another are the most common cause of a half-empty first session.
Charleston, Decatur and Champaign are close enough to draw from for a day rate, and to fall back on if Mattoon has nothing free on your dates.

The local constraints
No published capacities
Not one Mattoon venue publishes a capacity in the open sources behind this page. Every room on the list will quote you a number directly, but you cannot compare them before you call, so build a fortnight of venue calls into the plan.
Arrival is a half-day
62 km (39 mi) from CMI means most attendees lose a morning to travel. Open registration the evening before and put nothing you care about in the first slot.
Pricing this against a real Mattoon room
Take 240 people through the door in Mattoon — a mid-sized Mattoon programme, since no Mattoon venue publishes a capacity in open data. 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.
- activated attendees
- 240activated attendees
- billable, after the first 50 are free
- 190billable, after the first 50 are free
- for the whole event, at $5 each
- $950for the whole event, at $5 each
You are billed for people, not for the venue, so the room you choose in Mattoon does not change this figure. Nothing is charged for an attendee who registers and never opens the app.
Matching the room to the format
No capacity is published for any Mattoon venue, so match the format to the room on your site visit rather than to a number on a listing.
- trade shows and exhibitions
1 exhibition or convention hall means a booth plan is possible in Mattoon without renting a marquee.
- multi-track conferences
The exhibition space here doubles as plenary space when the floor is cleared.
- association annual meetings
An association meeting needs one big room, several small ones and a hotel block, which is the combination Mattoon is set up for.
- training days and workshops
1 purpose-built function space is the easiest kind of room to run a workshop in — the power and the load-in already assume it.
- leadership retreats
Smaller rooms suit a retreat better than a hall does, and Mattoon has them.
