Why don't you do the obvious and write down where everyone who definitely wants to come to the AGM is from?
That was the general idea with my map (although I decided not to specifically restrict it to people that wanted to come to the AGM because my hope is that if we choose a good location it will encourage people nearby to come even if they weren't planning on it).
