I think that CM's spread these stories to try to build up the magic of WDW.
A CM once posted that they were told in their orientation class (traditions?

) that the rooms in the Contemporary were modular and they could completely replace all the rooms in one day and therefore do a complete room remodel with only shutting down the resort for a day. But they tried once to do this and it didn't work because the building had settled.
This of course is false, yes the rooms were pre-built on site and installed with a crane but this was to speed construction not to make them so they could be removed.
