Access and arrival
9 km (5.6 mi) separates Fort Armstrong Theatre from Quad Cities International Airport (MLI) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.
The centre of Davenport is 1.6 km (1 mi) away, which is a taxi rather than a walk and a reason to publish an arrival map.
Davenport has 21 venues mapped in total and a population of 100,938. The Davenport guide covers the airport, the local time zone and what else is bookable nearby.
The kind of event it takes
This is a room for a workshop, a chapter meeting, a training day or one track of a larger programme. Anything with an exhibition attached needs a second space.
- networking mixers
An independent space with its own character, which a mixer benefits from more than a conference does.
- fundraisers and galas
A room with a personality is worth more at a gala than square footage is.
The app bill, at this size
Take 240 people through the door in Fort Armstrong Theatre — a plausible programme at a venue of this kind in Davenport. The first 50 activated attendees are free on every event, so only the rest are billed, and the total stops moving at 1,000 however many more turn up.
