I both agree and disagree with you. Obviously if the TV was in the DINING HALL they would put it on CNN as that is a popular channel and its what most adults would want to watch. And as for kids watching it in the dining hall, I don't think they would be watching TV. They would be more absorbed in the greasy mass on a tray infront of them.

However, if the TV was actually IN the PlayPlace, then the adults wouldn't be watching it so it should really be set to other programmes such as Nickelodeon. But even in the PlayPlace, I doubt the children would be watching the TV as they have a TV at home and have better things to do anyway, such as discovering new found worlds in the giant hamster tunells.
