According to the weather forcast for Orlando, which I get in my inbox three times a day,

the daytime highs this week are in the 30's with the lows being in the low 20's. I don't think you'll need a lot of warm clothes at all, just for the drive if you are driving. We go in two weeks and I'm not taking much warm clothes at all. It can get cold in November but I'm hoping it will be awesome weather.
Besides, you can always head over to the GAP, Old Navy and OshKosh outlets to pick up some clothes for the kids if you need some. They have great deals there!!
Have a super trip and tell all "my friends" that we'll be there soon!!
Here is what I got in my inbox this Wednesday Morning.
