Honestly I wonder if it might even be a Hollywood exclusive; given all they would really need to do for the moment is to preserve the core elements from the layout that remained intact for UHH, and simply restore them to what it was when Evil Dead Rise was coming.
It feels like the kind of a cost-saving move that honestly would be welcome and good for the scenario of Halloween Horror Nights for the budgetary. I'd also imagine that Hollywood and WB would've had some form of contract that ensured things to be proposed later should it fall at the point that it did.
To ask this question albeit though, and it's a good one: Do we think they could go to 9? Murdy has talked about in the past that Jurassic World doesn't seem to be a venue that's as impossible to use, and the only issue that could come is in simply queue placement.
If they can, I could easily see it handled similar to how Curious George is; with the entrance for the house over at the Super Nintendo World backstage gate like how the path to Curious George is next to Potter.
