I'd say any of the hotels/motels on site would be fine.
They're all built to withstand hurricanes and, in addition to that, you're pretty far inland.
I wouldn't want to be in Ft. Wilderness either camping or in the cabins (I think the cabins are portable). Also, with all of those trees and the fact that that area really doesn't get hit a lot there's more of a chance of downed trees which could suck if they hit your cabin, campsite, or block the road.
The "cabins" are one bedroom single wide trailers. Not the place to be in a hurricane.
Me? In a one bedroom DVC villa...because I'd have a full kitchen and it would be thoroughly stocked. And praying I don't loose power.
