Where the largest programmes go
Nothing in Ottumwa is classified as a convention or exhibition centre, so the largest rooms here are arenas, theatres and function spaces. The ceiling is 275 seats, at Dalby Hall (Rich and Gail Dalby Meeting Hall).
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.
Travel, time zone and arrival
Des Moines International Airport (DSM) is 119 km (74 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.
Newton, Kirksville and Iowa City are close enough to draw from for a day rate, and to fall back on if Ottumwa has nothing free on your dates.

Worth knowing before you sign
No exhibition hall on record
Nothing in the Ottumwa dataset is classified as a convention or exhibition centre, so a trade floor needs either an arena floor, a fairground, or a nearby city. Check the arena listings above before you promise exhibitors a booth plan.
The ceiling is low
The largest stated capacity here is 275. Above that you are combining rooms, running sessions in shifts, or looking at Newton.
Arrival is a half-day
119 km (74 mi) from DSM 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 Ottumwa
A Ottumwa programme at 280 activated attendees — sized to Dalby Hall (Rich and Gail Dalby Meeting Hall), the largest stated capacity in the Ottumwa dataset — prices like this. Nothing is charged for the first 50, and nothing at all is charged past 1,000.
- activated attendees
- 280activated attendees
- billable, after the first 50 are free
- 230billable, after the first 50 are free
- for the whole event, at $5 each
- $1,150for the whole event, at $5 each
