Does Columbus day or F&WF effect crowds? DH does not like waiting in long lines, so typically lines longer than 1 hr are skipped. He says it waste too much time standing for 1 hour that last 5 mins when there are PLENTY of other things to do and see. What are line like this time of year?
I gone have during the week of Columbus Day the past 2 years. I like only having to take off 4 days from work to go

I can say that the weekend and the Monday holiday are quite busy at the parks, especially EPCOT. The Food and Wine Festival attracts many of the Florida Resident passholders on the weekends, so that coupled with a holiday weekend can make for some longer lines. But I never found them unmanageable, and the FWF is more about eating and drinking around the world, not going on Soarin'.
Even with the crowds, the fact that you get FWF makes October a better choice. Maybe hit AK or DHS on the weekend and save EPCOT for midweek.
The weather is better IMO in October. September high avg. is 90, low is 72. October high avg is 85 and low is 65. And historically September is a wetter month as it rains about 3 more inches than October.
We are going in September this year only because I was able to trade my timeshare into the Boardwalk. Otherwise, it would have been October again. FWF will be missed

, but at least we'll still get to go to MNSSHP in September.
The only other time I went in September was in '04, about a week after 2 hurricanes hit central FL in a row. Hoping for good weather this September.
