I'd like to hear from some folks who were at WDW during Charlie. Charlie is the one that really made a mess of Central Florida. My mom's ex was still living/working down there and, from what he said, that's the one that really was the eye-opener. No gas at local stations, no power for a while, etc. None of that stuff sounds that out-of-the-ordinary to us because we've done the hurricane thing a lot (Ivan w/our folks in south Alabama, Katrina at our house when we lived in Louisiana, and Ike at the house we currently live in...just to hit the ones that were the most adventure). I think doing a storm at Disney would be interesting just because we wouldn't have the benefit of our generators, window units, camp stoves, dozen 5-gallon gas cans, etc. It'd be a new routine.
For those who will be there, don't sweat it. The track the storm is on will likely not bring the crazy wind you have to run from. The location of WDW will make the storm-surge a non-issue. Think of it as an adventure. Go outside when you can, watch what Mother Nature can do, and take it all in...especially if you live where hurricanes & tropical storms are something you only see on television. I've lived in close proximity to the Gulf almost my entire life. Our rule of thumb is: Category 1 = fun to watch, probably will find a good place to get outside to feel it. Category 2 = fun to watch, probably won't be outside as much but still will go check it out. Category 3 and up = pack the car, we're out.
