I'm picturing the restrooms in the Land. There are benches on the far wall, not where guests line up.
I'm also picturing an area like the Nemo show queue. The queue itself doesn't have benches, but benches are within view.
I'm also picturing some of the bus stops, like at the resorts. Where some guests line up, and some sit on the benches. I have seen plenty of disabled/senior guests blocked from boarding the bus by able-bodied guests- even though grandma arrived far ahead of the able bodied guests. when they finally board, the able bodies guests have hoarded all the seats.
I think the guests who rush the bus are the ones that are being rude in that situation, but they DO justify their conduct by insisting the elders were not standing in line.
Worse, some of the selfish guests hog empty seats with backpacks!
Mind, (I'm fairly confident) I have seen pure line-cutters WDW. I also don't think the OP should do as she proposed.
