Then don't allow children in to an event that isn't suitable for them.
This is the difference between Universal Studios Halloween Horror Nights and ScareFest. Universal close the park, then re-open as a Halloween only event, ensuring there are no young children in the park. Alton Towers run scare zones all afternoon, therefore they need to have clearly defined entrances and exits so that younger guests don't have to or can't enter.
I don't think that AT could close the park and run an even only Halloween event, Thorpe have done summer evening events that haven't been popular and AT is even harder to get to/from. Many people won't want to stay in the park past 9pm due to long journeys home.
