SAFD:
Whenever I consider the loss of an attraction my mind immediately pivots to “If not (insert attraction here), then what?” I think, too often, the reality is that “Nothing” is Disney’s answer.
For Carousel of Progress my answer would never be complete elimination. The footprint it occupies is quite small, so the opportunity to replace it with something “better” would be a questionable prospect.
For an update, I’d be much more interested in the theater and seats being given periodic updates than the scenes being completely redone. If there are script elements or scene elements that should be changed I’d deal with them individually. I’m okay with the timeframes as they are, the mid-century modern prediction of the future that somewhat permeate both MK and Epcot are fine with me as a representation of the parks when they were built. I’d be much more interested in tlc being given to the attraction than an overhaul.
It would be nice if Disney were reinvesting the revenue the parks are generating into the attractions and cast members that make those profits possible rather than redirecting and doubling down on their other businesses. Such is life, I guess.
