I've never stage doored for Stephanie specifically for a matinee show, but my guess would be she would come out. I've only ever heard of her not coming out the stage door twice (once was the closing of Pirate Queen and the other was when she got hurt). Stephanie is the most gracious person to her fans I have ever met, and I would imagine she would come out between shows, unless of course something else came up.
"This table, he is over one hundred years old. If I could, I would take an old gramophone needle and run it along the surface of the wood. To hear the music of the voices. All that was said." - Doug Wright, I Am My Own Wife
