I would be curious to know if line cutting has increased since Disney introduced LL into the parks mix. Lightening Lanes and before that, although to a lesser extent, Fastpass, have taken away the "fairness" of waiting in line.
Most families who go to Disney are not like the people on this board. Disney, to most people, is not a, "well if I don't get to go on the ride this time, I can go on next time." It is a once or twice in a lifetime trip. And, it is expensive. And, people not knowing all of the tricks to how "to do Disney the right way-" often don't get to see everything they want to. Spending a lot of money and then not having your expectations met, can be frustrating.
Add to that, if your family is watching their budget and can't afford LL, I could see how anger in some people could grow, knowing that because they can afford to, others are "cutting the line" with LL.
I wonder if some families get to the point to saying-I am not waiting this long in line one more time-let's barge to the front.
Just a thought.
