To give some additional details to just where the mazes will be located, as far as I understand.

FX's American Horror Story: Asylum - From Dusk Till Dawn Tent
Warner Bros IT - Soundstage 747 Parking Lot
Trick r' Treat - Metro Set's Tent
Lower Lot
John Carpenter's The Thing - Revenge of The Mummy Overflow
Upper Lot
Stranger Things - Waterworld Outdoor Queue
Universal's Classic Monsters - Parisian Courtyard
Unknown
Blumhouse's Halloween - Unknown
This year, as far as I understand, will be the first time that River Adventure's overflow will not be used, since before Alice Cooper's Welcome to My Nightmare from 2011.
This year will also be only having two exclusive IP, in the form of Universal's Classic Monsters, and American Horror Story: Asylum. I am not going to clarify on Orlando as of now, but that this year should bring the event to have similar marketing strategies to each other, similar to last year's Holidays at Universal Parks and Resorts at Hollywood and Orlando.
And now, unless if anyone figures out Beginning or Curtains, I am out of the discussion ring for Halloween Horror Nights 2018, until I can speak about the lineup more publicly than this. I have never done anything like this before in the scale, so I thank you all for pitying me for just a few.
