We were there Nov 2001. There was NO lines (relatively) anywhere! Most we waited was 15 minutes for an attraction. Keep in mind this was just after 9/11. My DD and I went again in Oct 02, still not bad for crowds.. not packed by anymeans, needed to fastpass some attractions. We are going again this Nov... getting anxious already!
Weather is comfortable to hot during the day (80's) not much rain when we were there. Got very chilly in the evening, we had to buy some sweaters.
Nov will be my 5th trip in 3 years.. I feel I haven't even come close to seeing/experiencing all WDW has to offer.. I would encourage you to extend your time, slow down, and enjjoy the details..
See you there!
