I've probably been involved in a couple of dozen of these with the Chesapeake woodturners in Maryland and local clubs here in Fla.
If you have 1 or two folks willing to cover all time slots it can work well.
A sign-up sheet with time blocks works great
You then know where to plug in the 1 or 2 willing to cover the open slots.
2-4 hour shifts 2-3 people per shift and a lathe to make chips.
a table to display work, club promotion material. The AAW will send you a packet to set out. We use the folding foam board display with photos from classes, demos and a few printed pages. You can use this over an over.
What we have done for the Tampa Woodworking Shows is to involve three clubs. One club could not support the three day commitment with three clubs we have at least 4 folks in the booth at all times and frequently have 6.
But many of the time slots have no one from a particular club.
This has a side benefit that we get to know people in the other clubs.
In my experience
The Woodworking shows are the top place to find new members and the audience is interested in technique
State and county Fairs - mostly folks just want to be entertained
Craft shows- a lathe attracts folks and usually you get good sales.
have fun,
