Personally, I like Fury and GateKeeper over the entrance to those respective parks. Both are stunning in those spots. I don't want that for KI though. I think maybe a refresh on the entrance building perhaps, but I love walking through and seeing the fountains and tower unfold as it has been since the park opened.
I would much rather see an amazing coaster installed into The Vortex's old site. It feels barren along that walkway from Rivertown to Coney without a major coaster in the spot. And of course, without my beloved Flying Eagles also. I'm old enough to have ridden the original Bat and Vortex. So, to me, that is sacred coaster ground. My personal wish is for something along the lines of Maverick or next gen version of a multi launch, or a ground-up RMC (one can wish).
