I don't really know about hurricanes specifically with weddings, but having lived in Orlando during the hurricanes of 2004 I can tell you that Disney is the best place to be if you have to ride it out! They have their own power plant and when every other place (including Universal) goes dark Disney still has power. They don't shut down the resorts due to hurricanes and they manage to keep everyone entertained and calm. They did close the parks for 3 days in 2004 due to hurricanes but I don't think they closed in 2005 - I could be wrong but I don't remember them closing last year? If you're having your wedding at a resort you should be fine. I don't know about the WP? The only real "problem" is if your guests cannot get to Florida because of a hurricane. There was a bride on these boards that happened to, they held the wedding but only a few guests were able to get there. She was married the week after my wedding when Wilma hit last year and I know we ran into problems with our honeymoon cruise, which worked out for us, but it was a hassle.
Don't worry about it too much, there's nothing you can do to stop a hurricane, just plan your dream day and try not to think about something bad happening (I know, easier said than done!). Most of the hurricanes the last couple of years seemed to hit early fall if that helps!
