Where do actors typically hang out when they are not on stage for an extended time?

Actors typically hang out in the green room when they are not on stage for an extended time because the green room serves as a designated space for the cast to relax, socialize, and prepare before and after performances. It is often equipped with comfortable seating, refreshments, and sometimes mirrors for touch-ups right before going back on stage.

While dressing rooms are also used by actors to prepare for their roles and often include personal items and costumes, they are more focused on individual preparation rather than relaxation and socialization among the cast. The costume and scene shops are specialized areas for the creation and maintenance of costumes and sets, respectively, and are not designed for actors' downtime. Thus, the green room is the most appropriate answer, serving its unique purpose in the theatre environment.
