I was on vacation at WL during Hugo. That was my first hurricane experience at Disney. We could hear some trees falling during the night, but that one turned out not to be serious. We learned about taking food though, as the boxed lunch at Whispering Canyon was, to put it bluntly, disgusting. I imagine that was Disney's first hurricane experience as well, although I don't know for sure.
I'm definitely packing as much food as possible, I already have dietary restrictions that were making planning my meals/reservations a bit of a puzzle so I am dreading being stuck with crappy food I can't even eat. My solution if it comes to that is bringing tupperware containers with me into the parks in my cooler backpack, and getting plenty of food to go when we leave for the evening
