I'd love the idea of this, but I wonder if the when the ride stops the games stops too!
I have been stuck on numerous rides, mainly at Six Flags Great America. However at Disney World I've had the joy of being stuck on It's A Small World in the room just before the exit tunnel for what was 20 minutes with the song just going over and over and over and over and over and over and over and over and over and over and over again.
Was also stuck on Living with the Land right out of the gate for about 10 mins just watching the rain scene.
Been stuck on the People Mover in the Space Mountain Tunnel for 15 mins, however Space Mountain was still moving and dark, this was just as bad as It's A Small World because the cast member kept making announcements that the ride could restart any moment and you need to sit your butt down (in a nicer way) and the speakers were on at full blast, or she was yelling into the microphone, either way it hurt your ears with every announcement.
While not stuck on the ride, I did get to experience Test Track at Walking Speed till it was time to run the loop outside. Imagine the horror of essentially walking into the Semi-Truck and slowly swerving away. I don't know what happened that ride, but it was like being stuck behind an old granny who could barely see over the driving wheel on the actual road.
