My DD 4 1/2 and I are headed to WDW Dec 6-14. It is the first time for the both of us! I've been to DL several times but never the WORLD. So it will be a great memory making GIRLS ONLY trip for us! But, I am concerned about what to pack. We are from Michigan.....so Florida will be a lot warmer than Michigan at that time of year! Do I pack more jeans or shorts? Do a bring a winter coat or pack sweaters and a light jacket? What about swimsuits...should I bring them? I'm confused. I would love everyone's input. Also any other WDW tips or suggestions for a newbie would be greatly appreciated. Thanks!
