@MetroWest Here's what I deduced about house locations/entrances. This could be wrong or different from previous years.
Bride of Frankenstein - Soundstage 23 near the front of the park. This soundstage hasn't been used since The Thing in
HHN 21. It's behind the amphitheater in front of Rip Ride Rocket. I presume the entrance will be between Fallon and the amphitheater, just in front of the Fallon bathrooms. However, they usually have people line up in the grass in front of the amphitheater. Maybe the same entrance as Stranger Things first year.
Texas Chainsaw Massacre - Also soundstage 23. I think it will use the Jimmie Fallon entrance and go through the building. I can't remember if that's were you entered for Yeti last time.
Toothfairy & Icons - Soundstage 24. I believe this is the entrance between Fallon and the Tribute Store underneath Rip Ride Rocket. I believe the entrances for both are right next to each other but split off in different directions.
Scarey - MIB tent. I think the entrance is between MIB and Fear Factor. House of 1000 Corpses was there last time.
Wicked Growth - Sprung tent 2. This is where Depths of Fear was last. You enter between MIB & the Coke store, right before entering Springfield. The entrance should be next to Puppet Theater.
Puppet Theatre - Sprung tent 1. This is where Nightingales was last time. The entrance is between MIB and the Coke store, right next to Wicked Growth.
Haunting of Hill House - New parade building/B108S. Universal Monsters was there last. The entrance is in Kidz Zone to the left as you enter the area.
Beetlejuice - Parade building/B-79. Graveyard Games was there last. I think the entrance is right next to Hill House. I believe Graveyard Games and Universal Monsters had entrances right next to each to the left as you enter Kidz Zone. The exit is through the ET outdoor queue.
Case Files Unearthed: Legendary Truth - Soundstage 40D/Shrek. This is one of the actual Shrek theaters; there are two. Shrek has limited capacity while HHN is occuring, since half of it is being used for a house. This was killer klowns last time.
