The crowds are great, its a wonderful time to go as everyone is gearing up to go for Thanksgiving. We love going this time of year, actually we go mid May and early-mid Nov. The weather can be iffy temp wise. One day we were in shorts and it was hot - the next day cold air came in and it got into the 50's and 40's at night. The GF was wiped out of sweatshirts! I would not call it very chilly, but cool. We also go there just before Thanksgiving ( I mean just b4, The Thanksgiving crowd is checking in as we are leaving - Yikes!) So you should have much warmer weather, I would pack a pair of jeans for everyone and clothing that can be layered such as t shirts and long sleeved shirts and a sweatshirt, just to be on the safe sideespically if you do E Ride Night. On a happy note, when the weather got cooler, it was beautiful....The sun was shining and there was not a cloud in the deep blue sky. I took the most beautiful pictures, they look like postcards. The sky was cloudless and the crowds were light - a photographers dream! I wonder if that's when WD photographers go out and take pictures, on days like that! You will have a great time early November!
