Our first trip we were at the Hoop Dee Doo with Princess Diana and her sons. William (10 at the time) actually participated in the show.
We saw Brittany Spears and Joey Mcintire (but that was a publicity thing)
our 2nd trip
A few years ago my kids with their significant others met Rob and Amber from Survivor and the Amazing Race (huge to me which is silly, but they were my favorite!) and we have a great picture of my daughter with the two of them.
Our last trip, my DD and I saw George Lucas at Beaches & Cream with his family and she talked to him briefly.
DD & I will be back in September, here's hoping?!...
