Many years ago we were in the All Star Music when a hurricane hit. At the time they told us it was the very first time WDW was closed for a hurricane. (although in the end, it did open that day, just several hours late)
It must have been more than 10 years ago.
Anyway, it was totally amazing how organized they were. Before the hurricane, they removed every single thing around the resort that was loose, including all the pool chairs. Completely removed them.
All around WDW, before the storm hit, you could see them 'battening down the hatches' so to speak. It was a major operation of incredible proportions when you consider how big WDW is.
