Limiting the number of tickets allowed in the park at any given time isn't gonna stop hoards of people coming in on peak nights to use their tickets only to be turned away at the gate. Even if the park prints that availability is limited on the tickets and park website, people are still gonna raise a stink if they aren't allowed in the park.
The best way to fix the problem with the crowds leaving Twas That Night would be to give everyone things to do in the area. Either open up Griffon or Alpengeist so that people aren't all trying to leave the theater toward the one exit at the same time. With Invadr opening next year, that would def help draw the crowds from the show toward that section of the park, but in the meantime, either run Griffon without the splash zone or have Alpengeist running to help balance the crowds out.
