Some of the parks make scooters and wheelchairs go through the main bus queues, with everyone else, and then pull them off to the side when they get to the end. I saw it once, while waiting for a bus to Pop. There was a woman in a small rented electric wheelchair ahead of us, and directly behind us was a pair of truly obnoxious creatures who kept carrying on loudly about "those people" and how "they should have a separate bus" so that they didn't hold up "normal people" trying to get onto the bus. The poor girl kept sinking lower and lower into her chair.
We chatted with her a bit, in a friendly way, but she was clearly feeling miserable about the jerks in line behind us. When we got to the front, the cast member directed her over to the side, behind two other families with scooters. It was clear she was going to have to wait for at least two more busses, before she'd get a chance to get on.
We thought we wouldn't get on either, so we hung back. But then the bus driver gestured to my husband and me and said, "Squeeze in!" So we did, and people made room for us. Then the Ugly Stepsisters charged up and said, "HEY, WHAT ABOUT US!?"
They definitely could have fit in with us, even though I saw my husband step back a pace to try to fill the spot behind him.
But I guess their tone annoyed the bus driver, because he looked right at them and said, "NO ROOM!" and closed the door right in their shocked faces.
Disney really IS a magical place!
Though it would have been nice if the poor girl in the electric wheelchair could have gotten back to the Pop sooner, too.
