In venues with limited wing space or awkward entrances and exits, the logistics of getting dancers on and offstage should be taken into account. It there is only a small door available, and this cannot be masked from the audience, exits can result in an ungainly queue or, worse, a pile-up of dancers waiting to get off. Dancers may also be waiting to get onstage. As well as being a distraction, this could cause injury if large numbers were involved.
