Where an exhibition fits
4 venues in Sedalia are classified as exhibition or convention space. They are the only rooms here designed around a floor plan rather than a seating plan.
- Fairgrounds Barnsize not published
- Expo Centersize not published
- Mathewson Exhibition Centersize not published
- Katy Trail Sedalia Fairgrounds Trailhead Parkingsize not published
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 Sedalia
Columbia Regional Airport (COU) is 88 km (55 mi) away, far enough that arrival day is genuinely a travel day and a first session before noon will lose people.
Local time is Chicago time (America/Chicago) — set every session time in the app to that zone and let attendees' phones do the conversion.
Warrensburg, Columbia and Jefferson City are close enough to draw from for a day rate, and to fall back on if Sedalia has nothing free on your dates.

Before you hold a date
No published capacities
Not one Sedalia 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
88 km (55 mi) from COU means most attendees lose a morning to travel. Open registration the evening before and put nothing you care about in the first slot.
A worked example, sized to Sedalia
Take 240 people through the door in Sedalia — a mid-sized Sedalia programme, since no Sedalia 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 Sedalia does not change this figure. Nothing is charged for an attendee who registers and never opens the app.
Which kind of event this suits
No capacity is published for any Sedalia venue, so match the format to the room on your site visit rather than to a number on a listing.
- trade shows and exhibitions
4 exhibition or convention halls mean a booth plan is possible in Sedalia 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 Sedalia 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 Sedalia has them.
