Well, if someone at Disney told you that then it
must be true, right?
Seriously, is this really worth splitting hairs over? Initially they warned guests that there could be a problem with noise. Now they've decided to close off large sections of the resort instead. It stands to reason that by doing so, they no longer need to worry about the volume of the disruption. They can start and end their daily work shifts without regard for the impact on nearby guests. They don't have to worry about the impression left on guests by the construction workers or equipment sitting in hallways. They can disconnect power or water lines as necessary without worrying that nearby guests won't be able to turn on a fan or flush a toilet.
Why is this worth examining to the Nth degree? The decision has been made. Guests are being offered generous room upgrades elsewhere, or they can cancel their trip. No, it's not an ideal solution for those who were anticipating AKL, but things happen and Disney is being very generous in terms of the compensation being offered.
