I was curious how much the park really makes on the business picnics, etc. that go on in the festival arena now. B/C it seems to me that if there will be no show there, I don't really care about your business lunch - that's what the conference rooms at the hotels are for. The Festival Arena area is HUGE, and could easily accomodate a new attraction.
Also, I'd like to see BTR come to life. Whenever I walk by (and I always just walk by) I think of a field trip we always used to take to Oak Glen where we got to watch them make cider and help pick apples and see how old tools worked. How easy would it be for Disney to get a few historians and some hands on old-west-y ranch equipment for people to mess with? I've watched kids spin in a circle on Pirate Island pulling up the chest enough now to know that they'd do the same thing in Frontierland braiding their own rope. Fun, educational, and the cheapest overhaul Disney would ever do.
