The problem is if you are lineament and have an exception you will have people using that exception to the detriment of others much as you had people in the past that would hire a person in a wheelchair to go with them to Disneyland so they could jump all the lines. It may suck for people if the rules are strictly enforced but it also eliminates the ability of people to game the system at the expense of others.This is a REALLY good point that I don’t think has been brought up yet.
This violent family - imagine if one of them had to pee while in line, but the CM wouldn’t let them return because that was an official rule by Disney. Do we really think the family wouldn’t have tried to beat up the CM just as they did this other family? You think they’d just be like, “oh okay, rules are rules, we’ll just get in the back of the line and wait all over again?”
Instead of this thread, we’d have a 30+ page thread about whether or not Disney SHOULD be lenient about letting people return to their spots in line for bathroom emergencies and other innocuous reasons (like a left behind valuable on a stroller). And in fact, I hypothesize that the thread would be even longer, as people would pile in here to tell their stories of their three year old pooping in the queue or how they wasted 90 minutes in line because they suddenly got diarrhea, had to run to the bathroom, and the CM laid down the law when they tried to return and they were forced to get in the very back of the line. I’d imagine it would be a much more angry and exasperated thread than we currently have.
You can even look at it as a learning tool to teach people not to forget things or to go to the bathroom before they reach the point of having to run to one before wetting themselves.
