Backstage to Onstage

To understand a person’s performance, the audience will first observe the social front that defines the individual. This can be broken into two parts: setting and personal front. Setting is defined as the space an individual occupies during his performance. It generally stays put, so performers must come to the place to act and then terminate the performance when leaving.
Disneyland implements setting to distinguish areas of interaction with guests, with cast member break areas. This is why there is a separation between backstage and onstage in the layout of the park. Only the cast members are allowed access to both sides of the performance, while guests are only allowed in the stage area. This creates the illusion of reality for the audience, because they are only exposed to one side of the performance and must take it as the truth.
Cast members can then begin their interaction fully ready from a hidden door or down a corridor guests are not allowed access. It is unknown by the audience the exact nature of how they begin their performance as they seamlessly take over positions and perform tasks guests do not bother to scrutinize. You do not notice the custodian who sweeps up a napkin or the security guard in plain clothes doing surveillance down Mainstreet USA. And why should you?
Your role as the audience is to understand that this is all a show with every individual playing a part, with certain mysteries as to how it all comes together. By allowing the individual to wonder about its innerworkings, Disneyland is able to keep the magical aspect of a theatre show.
