So with Dead Creek Wood presumably taking place in Zombie Hunt's route, I'm guessing Blair Witch will take place from roughly the Zombie Hunt exit, and ending at the shed. That creates a very short attraction..
My bigger concern is how congested that stretch of the park will be. You'll have Blair Witch and Vulcan Peak in the same area, Dead Creek exiting there, and then further along, you've got the entrance to three other mazes all in pretty close proximity. It seems like it could be a recipe for disaster.
They really need to find a way to use the beach again. I know they had major flooding issues, among other things, in 2015 with Big Top, but it was more or less okay 2008-2012 with Curse and Se7en. Yes it will almost definitely require tents, yes it will require a lot more money, but it'll spread attractions round the park and utilise a massive space prime for an indoor attraction.
