DD was 11 when we went in February. She liked it. I found that it got the whole family to spend more time in each country. While she waited in line or was coloring, DH and I strolled about "window shopping".
It was neat to happen upon Belle, Mulan, Princess Aurora, Tigger, Pooh, and Eeyore all just by strolling about looking for the KidCot sections. We didn't plan to find characters this trip, we just seemed to always be in the right place at the right time.
Have fun!!! We cannot wait to go back.
