We did the Hoop De Doo when my little princess was 2 and then Mickey's Backyard BBQ when she was 4. She liked the HDD but LOVED the MBYBBQ.
The HDD is fun, but it is cowboy, cowgirl type of slapstick comedy with some interaction with the crowd.
The MBYBBQ has tons of crowd interaction. Kids (and some of us adults) get to get up and dance with Mickey, Minnie, Goofy, etc. These characters spend a lot of time dancing with the kids.
My 1 year old little princess even had fun out dancing around. She would have been major crancky sitting in the chair at the HDD all that time.
In my opinion, the Backyard BBQ was a lot more fun for the little ones.
