I saw the show back on Black Friday. At the stage door, the guards there announced that neither Jennifer or Cynthia would be coming out that evening. My mom, aunt, and I decided to wait anyway. A woman came out of the stage door and started handing out playbills signed by Jennifer. Then Cynthia came out along with Danielle on a hoverboard. As they were signing, all of a sudden Jennifer came out and spent so much time signing for everyone. Once the actresses finished signing and left, mostly everyone left and they took down the barricades. But we waited a little longer and a lot of the rest of the cast came out and they were more than happy to to sign for everyone who was still waiting.
This was almost a month ago, so I don't know if everything it still the same, but that's how it all played out for me. Enjoy the show! It's amazing!
