Getting attendees to O'Fallon
St. Louis Lambert International Airport (STL) is 30 km (19 mi) out — a normal airport transfer, worth an hour in the run of show on the first morning.
Local time is Chicago time (America/Chicago) — set every session time in the app to that zone and let attendees' phones do the conversion.
Saint Peters, Wentzville and Saint Charles are close enough to draw from for a day rate, and to fall back on if O'Fallon has nothing free on your dates.

Things that catch organizers out here
No exhibition hall on record
Nothing in the O'Fallon 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.
No published capacities
Not one O'Fallon 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.
The city is smaller than the market
95,355 people live in O'Fallon itself, but about 2.8 million live in the wider St. Louis, MO-IL. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
The bill for a O'Fallon programme
Suppose 240 attendees claim their invite and open the app at a O'Fallon event a mid-sized O'Fallon programme, since no O'Fallon venue publishes a capacity in open data. Here is exactly what event67 charges, with the free 50 taken off the top.
- 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 O'Fallon does not change this figure. Nothing is charged for an attendee who registers and never opens the app.
What sort of event fits here
No capacity is published for any O'Fallon venue, so match the format to the room on your site visit rather than to a number on a listing.
- 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 O'Fallon has them.
