Just returned from a 7 day trip with my 14, 12 & 9 year old. Let me tell you, I'm 43 and I ran circles around my oldest 2! They just wanted to sleep. Next trip, I will not plan any early mornings! I went from early morning until late at night, but not those two. I really identify with you and hope you can have a good trip. My 14 year old does enjoy the World Showcase. Have you tried that with her?
