Looks like this article has shown us of what they gonna have for this Halloween this year.
Disney visitors to be screaming for more - The Standard
This Haunted Halloween will see the theme park launch a "Scream-No-More Challenge" - to test the ability of visitors to fight fear, and the urge to give full play to their lung-power.
Checkpoints would be located in the seven themed areas throughout the park, where waiting in dark corners to scare the bejesus out of funseekers will be the likes of cannibalized Babyhead - lurking in Toy Story Land, or extraordinary beings in Adventureland.
This sounds as they are putting more event. Thanks to the three new lands. With it, they'll open the park till 11 pm from oct 4 - oct 31
