I will keep you September travelers in my prayers. I went to WDW in Sept of 2004 during one hurricane and left before the next hit, but I have to admit, it was probably our best trip ever. The crowds were low, very low and the weather was good after one bad day. WDW didn't loose electricity since theirs is underground. They took care of everyone including employees allowing them to come stay at the resorts with thier families and pets. They had characters in the lobby of the hotel playing games with the kids. I was very impressed.
Good luck everyone and try not to worry......
