I know this is not comforting and might sound a little wierd, but pray for that hurricane to hit while you are there,
we went during a hurricane - WOW no one was in the parks and we only suffered a slight rain here and there during the trip. Although the waterparks were unpredictable on when they would be open, the major 3 parks (AK was not yet built) were empty, we kept running into the same families over and over, we stayed on MANY rides without even having to get off: Haunted Mansion, Astro Orbitors, Alien Encounter, Splash Mountain, Big Thunder Mountain and on and on.... even when we had to get off of the rides we just got right back in line and only waited a couple min. to get experience the ride again.
I have pictures in my scrapbook of main street nearly empty. NO lines for any of the characters. I mean it was literally like having the park to ourselves. It was my DH's first trip and we had a BLAST. Since most of the rides are inside the rain hardly was a factor.
Again I know that is not comforting and no one likes bad weather, but if it does happen, look at the bright side, you might end up with a lot less of a crowd, cause all the locals will stay home.
Just keep smiling... and saying "We are at Disney"
