We took our then 17 year old son who thought Disney was "stupid" and was only along because we promised him Universal (which, BTW, he thought wasn't as good as Disney - smart kid). He really did NOT want to go to Hoop Dee Do. Thought the whole thing was lame and complained the entire time we were there.
Until the show. I never saw that kid eat so much and actually ask for seconds on *gasp* a vegetable! By the end of the night, he was fighting us for the washtub we were given so he could play it himself. He tried to outsing us, outclap us, and outyell us because we were smack dab in the middle of the floor so my husband and I were on one "side" and he was on the other. And I'll never forget his face with the finale. Seeing our server up there and then getting dessert.
Price of Hoop Dee Doo - $60 (or so). Having your almost adult son having fun with his parents - Priceless.
