Where the largest programmes go
Nothing in Petaluma is classified as a convention or exhibition centre, so the largest rooms here are arenas, theatres and function spaces. The ceiling is 720 seats, at Phoenix Theater.
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 Petaluma
San Francisco International Airport (SFO) is 72 km (45 mi) away, far enough that arrival day is genuinely a travel day and a first session before noon will lose people.
Local time is Los Angeles time (America/Los_Angeles) — set every session time in the app to that zone and let attendees' phones do the conversion.
Novato, Santa Rosa and San Rafael are close enough to draw from for a day rate, and to fall back on if Petaluma has nothing free on your dates.

What to check before you commit
No exhibition hall on record
Nothing in the Petaluma 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
72 km (45 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
59,393 people live in Petaluma itself, but about 485,000 live in the wider Santa Rosa-Petaluma, CA. 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 Petaluma
Suppose 700 attendees claim their invite and open the app at a Petaluma event sized to Phoenix Theater, the largest stated capacity in the Petaluma dataset. Here is exactly what event67 charges, with the free 50 taken off the top.
- activated attendees
- 700activated attendees
- billable, after the first 50 are free
- 650billable, after the first 50 are free
- for the whole event, at $5 each
- $3,250for the whole event, at $5 each
You are billed for people, not for the venue, so the room you choose in Petaluma does not change this figure. Nothing is charged for an attendee who registers and never opens the app.
Which kind of event this suits
720 seats is the largest room on record, so Petaluma suits a training programme, a regional chapter meeting or a single-track conference rather than an exhibition.
- award ceremonies
1 fixed-seat house gives you a stage, lighting and sightlines without building any of it.
