I know! I'm freaking out! I'm hoping that it's the weekend and not the whole week that's going to be crowded. I am worried, though. It really seems like the first week in October is going to be packed.
I just found out today that Florida has its Fall Break one week (9/26/-9/30) before Kentucky's Fall Break (10/3-10/7). That would probably account for a lot more "local" WDW crowds than you would expect to see the following week.
