You could get some white leggings to keep her legs warm and let her pick out disney jibbits at the huge store on main street; that'll make the crocs fun for her too. We were there the first week of March last year and the weather was so mild that you wouldn't have needed tights. This is FL in the winter though so it is best to be prepared. Have a great time on your trip! I'm jealous you'll be there a whole two months before we get to go.
