imagine if they did what they did for walking dead in Hollywood but with potter....
And imagine if you could use your wands inside.... i could see people losing their minds at being able to shoot at Dementors with their wands.
specially if the wand effects were really simple with just pointing your wand. not having to move your hand to do the spell but just literally pointing the wand at a dementor or a creature and the creature flying away. it could even be done with some animatronics.
I dont know..... something like that could end up being really cool, OBVIOUSLY not as scary as HHN, but imagine if they made the sets like HHN and had dementor animatronics you could point at and stuff...
the lines for Gringotts and Forbidden journey are already kind of attractions on their own. some people enjoy the lines more than the rides sometimes (like with Gringotts) Imagine if they did something like those lines but with effects and creatures and special effects but you are just walking, i could see people freaking out over it
