Thanks for the advice but my 10 year old won't be a problem she has boundless energy, it is my 7 year old, she gets tired quickly and doesn't like being really hot so hopefully it won't be too hot when we go. I have a feeling I will have to
rent a stroller for her - how sad since she will be 8 when we go. This past summer we spent a day at Great America in Gurnee and it was probably the hottest most humid day of the summer and they were ok. Now I know the WDW parks are much bigger than Six Flags, but I'm hoping they will be fine me on the other hand maybe I should start walking everyday to get ready!
