I know the tower is an original part of the park, or near enough to make no difference, and I know I will get blasted for saying it, but I would not cry if they ripped it down. It is a terrible traffic block. In the future I could see a reno of the bath rooms that expanded the building. It could only work if they shifted the traffic flow to where the tower is.
I don't like the concept art at all. I think the big Griffon cutout will make the area look cartoony, and I really dislike how it blocks the window. Plus, unless other buildings in Aquitaine were repainted, the bright orange will look grossly out of place.
I do sorta like the name, though. "Griffon Lair" sounds pretty cool. I just hope the concept art doesn't reflect reality.
