Strangely enough, I kind of agree on the issue of obese people in
ECVs, which is just blowing my mind because I'm definitely pooh-sized and my mom would be one of those people in ECVs.
Still, I can see the point. Why should someone get preferential treatment because of something they did to themselves? Would an alcoholic get to go to the front of the line as well because they're too drunk to stand up straight?
The only problem with that, and the reason I still generally support letting them in, is that no one can tell exactly what their problems are. Suppose they're obese, but also were in a car accident and had to have their spine fused and that's the reason they can't stand all day--not simply because their bodies' can't support their weight. I don't think someone should have to give a full personal and health history before they get a Guest Assistance Pass, so I'm inclined to just live with in.
As for the rest of the line cutting, I would probably be OK with a small child who had a bathroom emergency whose parent is politiely asking to be let by. Other than that--no dice. If you chose to run off and get an FP, that's your choice and not my problem. If you couldn't keep your group together--not my problem. If you see your great uncle's neighbors 10 feet up the line and want to chat--not my problem.
I find the extra wide queues at Soarin confusing. If the queue is wide enough for 6 bodies, why shouldn't I pass people if there's room? I'm not talking about plowing people over, but if there's room in front of me, why not move up? The space is meant to be filled in, otherwise it would have been made single file.
