Good luck on stopping it as there is at least one ABANDONED vid that showcases this fact, including satelite images that show images that strangely look like a depression in the sand. another image with a metal wall is shown with depiction of support during demolition.
I am not an expert on sink holes but it was interesting when one showed up at a resort and took a condo down so it isn't like it can't happen.
also the rumour of the concern about the attraction having stess on the building structure did not come up with the building roof concerns, it was before this time. It just seems that there is a chronological history that points in a damaged building direction and as the building seems to have a very SUBSTANTIAL cost to build, it just seems odd that DISNEY would take such a large space down if there were nothing wrong with it. Then again in retrospect, they did destroy Pleasure Island and 20,000 Leagues and Journey.
I'm not saying you are wrong or that I am wrong, just repeating the vids.
