Despite its reputation, central Florida is surprisingly immune to hurricanes. The ones in 2004 were I believe the first big ones in recorded history, and obviously hasn't been anything near that since. Contrast that with, say, Connecticut, where we pretty much got a nasty one every couple decades (1938, Gloria, Sandy, I think there was one in the 60s).
The flip side of that is none of these "hurricane-proof" buildings has actually been exposed to a Cat 4. IF it hits Orlando fast and keeps that strength (which, again, we can't know right now), uncharted territory. I can't promise theme parks will be back to business as usual by Friday because no one knows.
