I don't think anything is going to settle down until Jan or Feb. I know they promoted the new Halloween decorations pretty heavily, plus with the start of the Dreams promotion, October has been more crowded than usual. As soon as the Halloween stuff comes down, the Christmas decorations will start to go up. The Christmas fireworks start Nov 10 and the parade starts Nov 17. The holidays will carry the crowds through about Jan 7, I'm guessing. Most schools don't start back after winter break until Jan 8. I'm thinking we'll see a drop in crowds then, or soon after.
Oh, and did some research after I posted on the pirates fastpass, they actually stopped earlier than I thought, in 2004, with the machines being removed in 2005.
