Interesting theatrical practice of allowing half price entry aftre the third act (if I read it rightly), - must have made a difference to how he constructed his play.

I notice in Sheridan's Prologue his warm commendation of the actors - and also "the principals" at the Theatre Royal Covent Garden (final paragraph of the Prologue)- is this also a reference to the actors, do you know Julie, or does it mean the management?
