The largest rooms on record
Nothing in Walnut Creek is classified as a convention or exhibition centre, so the largest rooms here are arenas, theatres and function spaces. The ceiling is 5,500 seats, at Saint Mary's Stadium.
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 Walnut Creek
San Francisco International Airport (SFO) is 42 km (26 mi) away, far enough that arrival day is genuinely a travel day and a first session before noon will lose people.
Walnut Creek keeps Los Angeles time (America/Los_Angeles), which matters most for the remote speakers you are dialling in.
Concord, San Ramon and Berkeley are close enough to draw from for a day rate, and to fall back on if Walnut Creek has nothing free on your dates.

Before you hold a date
No exhibition hall on record
Nothing in the Walnut Creek 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.
Arrival is a half-day
42 km (26 mi) from SFO 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
70,817 people live in Walnut Creek itself, but about 4.6 million live in the wider San Francisco-Oakland-Fremont, CA. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
