We're headed for our 1st WDW trip in less than 10 days now! I've been tracking the weather on-line and other than rain on Wed. it looks fairly good. Temps in the low-mid 70's. I've never been in FL. in the winter. What should we actually bring to wear? We're bringing our 5 & 6 yo DD and I have a bad habit of overpacking "just in case". Any advice?
