Playhouse Disney is a set of three vignettes told with one live performer and a bunch of muppet like puppets. The vignettes were of Sophia, Jake, and Doc McStuffins. In between, Mickey and the gang appears (also as puppets).
I would add that the benches are great, but they confetti and other things that fall from the ceiling generally do not fall in the back of the room. So, if your little one likes to collect confetti, just note that they will have to get up to collect it from the ground. When I was there, there were plenty of kids that got up to collect confetti, and the CMs didn't say anything. So it didn't seem like the CMs were expecting the children to stay seated the entire show.
