This is coming from a teen.
When I recently was on a trip to Disneyland with my school, I was embarrassed to be part of my group, at times. They were singing at the top of their lungs, shouting profanities, and just being super disruptive to the other guests. This could be fine at school, but not in Disneyland. Parents shouldn't be worried about 7th graders shouting inappropriate things in front of their small children on theDisneyland Railroad (which my group did.) Sure, maybe it'd be a tad bit more acceptable in line at California Screaming, or Tower of Terror, but Disney shouldn't be letting kids say those things with small children around them.
I'm not sure if they've ever had to threaten a group with expulsion from the park, but that should be the case. Whether it be with security cameras placed in rides, or cast members disguised as normal guests, these kids need to be kept under control, and have to face serious consequences if they go too far. It's a disgrace, seeing people behave this way with shirts that read my school's name.
Does anyone know if Disney has set up any sort of thing to keep school groups behaved during their visit? If they haven't, I real think the time is now.
