I'm trying to remember the first trip where we took the kids to HDDR. They are 8 and 10 now, and they've been at least 5 times already. I'm thinking that my younger DD was about 2 or 3 the first time we took them. I remember that they both loved the singing, dancing, hooting, and hollering, even if they didn't get the jokes. Every time we plan a trip to WDW, they beg me to please include HDDR in our plans because they both love it so much.
