Travel to Alton Chapter House
22 km (14 mi) separates Alton Chapter House from St. Louis Lambert International Airport (STL) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.
17 km (10 mi) from the centre puts this outside comfortable walking range of any hotel district, so the shuttle is part of the event rather than an extra.
Florissant has 6 venues mapped in total and a population of 51,290. The Florissant guide covers the airport, the local time zone and what else is bookable nearby.
What fits in this room
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.
