I would first get rid of snoopys starlight wall through thing. It just looks trashy and by the time it gets dark during the summer most familys have left the park and its just sits there.
I would also get rid of italian stunt track, i love this ride but it just doesnt look as good as it used too, the water spash down at the end is just a concrete pit now and the cars just look awful.
In this area i would put a ride like maverick or put a more family oriented attraction there.
The crypt building gone, i cant really think of a way to use it other than the haunt attractions, id just fill that area with trees and other plants to make river town feel more like it used too.
Id repaint The Racer and make one train backwards.
Id reopen SOB and remove congo falls and plant more trees in Action Zone.
This is what I would do, probably not what most of you would.
