They come close most of the time. My suggestion would be this...wear jeans, heavyish socks, a turtleneck with a sweatshirt over it and maybe a windbreaker if you have one. That way, when you get to WDW you will have warmer clothing. It saves room in your luggage also. You're going to need warm clothes to fly down in and to fly back home in...so this works well. And if the plane is chilly, and it always is when I fly, you have layers. You can peel them off if you get too warm. Just one piece of advice though...be sure to have a short sleeved shirt and a pr of shorts in your carryon bag. you will want to change when you get to WDW and your room may not be ready yet so you won't have access to your checked luggage. I've made the mistake of not having shorts with me and i looked like an idiot....80 degrees and I had on my jeans...almost sweated off 10 lbs that afternoon!!!
