Access and arrival

Seattle–Tacoma International Airport (SEA) is 18 km (11 mi) out, a standard transfer of twenty to forty minutes outside rush hour.

A central address is worth more than it looks: no shuttle, no parking plan, and evening sessions that people actually stay for.

The published number for the venue is +1-206-838-4333.

Seattle has 119 venues mapped in total and a population of 780,995. The Seattle guide covers the airport, the local time zone and what else is bookable nearby.

The kind of event it takes

Programme this as a theatre, because that is what it is. One track, one stage, an audience facing the same way. Catering and breakouts need a second space nearby.

  • award ceremonies

    Fixed seating, sightlines and a lighting rig are the hard parts, and they are already here.

  • product launches

    A single-track room with a real stage is the right shape for a launch.

  • multi-track conferences

    Works as a plenary house with breakouts booked elsewhere in the city.

The app bill, at this size

A The Triple Door programme at 240 activated attendees — a plausible programme at a venue of this kind in Seattle — prices like this. Nothing is charged for the first 50, and nothing at all is charged past 1,000.

You are billed for people, not for the room, so this figure does not change if you move the event down the road. event67 has no floor-plan or booking product — the venue handles the space, the app handles the people in it.
