The shows are 20 minutes long and start at 11, 12, 1, 2, 4, 5, and 6.
There is limited capacity.
It's pretty loud, so 1-2 y/olds might not dig it too much... depends on the kid really, but this is more of an active experience. Kids who like to dance (more than the dancing at Playhouse Disney) would like it. They teach you the dances and the characters dance with you.
Have fun!
