Where an exhibition fits
2 venues in Hermiston are classified as exhibition or convention space. They are the only rooms here designed around a floor plan rather than a seating plan.
- Umatilla County Fairsize not published
- Gilliam County Fairgroundssize 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.
Flights, time and distance
Tri-Cities Airport (PSC) is 49 km (30 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 Los Angeles time (America/Los_Angeles). Schedules published in one zone and read in another are the most common cause of a half-empty first session.
Kennewick, Pendleton and Tri-Cities are close enough to draw from for a day rate, and to fall back on if Hermiston has nothing free on your dates.

Things that catch organizers out here
No published capacities
Not one Hermiston 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
49 km (30 mi) from PSC means most attendees lose a morning to travel. Open registration the evening before and put nothing you care about in the first slot.
The city is smaller than the market
19,746 people live in Hermiston itself, but about 93,000 live in the wider Hermiston-Pendleton, OR. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
A worked example, sized to Hermiston
Suppose 240 attendees claim their invite and open the app at a Hermiston event a mid-sized Hermiston programme, since no Hermiston 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 Hermiston 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 Hermiston venue, so match the format to the room on your site visit rather than to a number on a listing.
- trade shows and exhibitions
2 exhibition or convention halls mean a booth plan is possible in Hermiston 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 Hermiston is set up for.
