And to let you in on the difference.
There is no need to talk down to me. I am giving you WoF's definition of Line Jumping. Take your children to the bathroom
before you get in line. If thirty minutes into an hour and a half line your child has to go again, that is different than purposefully cutting, and for some attractions it
can make a difference. For example: at some of my old attractions we do not have Flik, we have to eyeball the line and estimate the wait time accordingly. This does not work if peopel keep "catching up" with their parties. It is rude to the guests who were responsible and considerate enough to keep their families together who you then have to climb over. It is rude to the guests like Bru who use wheelchairs and then have to deal with you climbing all over them (read her incident report for just such an incident).
It does not take that long to get a FP that your family cannot wait for you, unless you are on the other side of the park, and then by the time you get there you are cutting through many people. By curbing this behavior it is harder for others to claim their party is ahead and line jump, and it can stop fights. I have seen guests get into fairly heated arguments over this behavior, and it can become dangerous. Case in point, the recent beating at the Teacups ride resulted from a very similar situation. There is nothing you can say to convince me that this acceptable behavior.
