Local time is Denver time (America/Denver) — set every session time in the app to that zone and let attendees' phones do the conversion.

The local constraints
No exhibition hall on record
Nothing in the Castle Rock 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 Castle Rock 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
57 km (35 mi) from DEN 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
83,213 people live in Castle Rock 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.
Pricing this against a real Castle Rock room
Suppose 240 attendees claim their invite and open the app at a Castle Rock event a mid-sized Castle Rock programme, since no Castle Rock 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 Castle Rock does not change this figure. Nothing is charged for an attendee who registers and never opens the app.
Matching the room to the format
No capacity is published for any Castle Rock venue, so match the format to the room on your site visit rather than to a number on a listing.
- community meetings
Nothing in Castle Rock publishes a capacity, so start with the format that scales down: a single room, one track, no exhibition.
- networking mixers
A mixer works in almost any room, which makes it the safe first event in a new city.
