Getting attendees to Diamond Bar
Los Angeles International Airport (LAX) is 56 km (35 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.
Pomona, Chino Hills and Chino are close enough to draw from for a day rate, and to fall back on if Diamond Bar has nothing free on your dates.

The local constraints
No exhibition hall on record
Nothing in the Diamond Bar 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 Diamond Bar 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
56 km (35 mi) from LAX 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
52,292 people live in Diamond Bar itself, but about 13 million live in the wider Los Angeles-Long Beach-Anaheim, CA. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
