The REAL story behind the Bride and the Attic -- the one no one is mentioning so far -- is this amazing fact:
The entire refurb was done without shutting down the attraction, and while hosting thousands of visitors per day.
In the past, Imagineers have shut down an attraction to tweak and test changes, and then opened it up.
In this case, however, as we've seen through our vigilant posters (the eyes and (mouse)ears of Micechat), the roll out was done gradually, slowly, and right in front of those who noted the daily changes. Presumably, this was done at night when the right closed.
I think this is a major accomplishment, and something that should be encouraged, and done, in future upgrades or remodels. Breaking down a remodel project into its smaller constituent tasks, and assignments, in small portions, allow visitors to enjoy the ride, while the refurbishment is going on.
It was smart to also lift the sheets and "unveil" (pun intended) the attraction changes midweek, so that if there was a problem, the ride can be shut down with a minimum of people in the park waiting for it.
I know that this thread will get responses like "that's impossible for larger refurbishments", and there are likely cases where that is true. But the effects in the attic, as unveiled, are VERY "major" for this ride, and I can't help but applaud the Imagineers who worked on this for the ride, and also hope that this is a trend that continues in the future.
Maybe we'll see purple sheets the next time Space Mountain or Pirates are being upgraded, and audio and track changes can be done in small segments at night while the ride is closed for the evenings.
