The shows last between 45 and 60 minutes. When you have a 6:30 show time, you are out in time for a 7:45 variety show/family karaoke/family dance, etc. with enough time to get to the next activity and even a quick clothing change if desires.
WIth late seating, we sometimes go to the show in casual clothing then change before the next activity.
If your interest is bedtimes for little ones, there are sometimes matinee performances too.
