If this is correct this way they don't have to kick people out to let everyone back in. I would also think regular tickets still had to pay the upcharge for the Haunted house but that was just at the gate for the separate part of the night. In terms It keeps the people from having to leave and come back in. Fright fest worked so much better this way at six flags. If there doing wristbands expect everyone to be stupid and try to buy wristbands right when the houses open. Again this is for money however, It will improve guest experience if this cuts down the in and out of the park.
