It is impossible to solidly predict future stage door climates. However, expect a madhouse at "A Steady Rain."
Also, I believe the actors come out after matinees of "God of Carnage," but don't quote me on that. I am also not sure which door they exit - there is an alley that at least two theatres share and there is also a regular stage door for the Jacobs Theatre. When I went to see "Three Days of Rain" the actors left the standard stage door; when I went to see "The Country Girl" they bolted out of the alternate alleyway, frankly, like autograph seekers were vermin to be avoided at all costs.
