How people reach Thornton
Denver International Airport (DEN) is 26 km (16 mi) out — a normal airport transfer, worth an hour in the run of show on the first morning.
The city runs on Denver time (America/Denver). Schedules published in one zone and read in another are the most common cause of a half-empty first session.
Westminster, Commerce City and Broomfield are close enough to draw from for a day rate, and to fall back on if Thornton has nothing free on your dates.

Before you hold a date
No published capacities
Not one Thornton 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
146,689 people live in Thornton itself, but about 3.1 million live in the wider Denver-Aurora-Centennial, CO. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
