Am I reading this wrong or not understand what they mean? The way it's written sounds like they are putting up to 6 people in one ride vehicle, and that they are combining groups to do so. Or do they mean one "train" of connected ride vehicles and that they are putting a group up to 6 people in one vehicle, leaving an empty one and then putting more in etc, but if you have a group larger than 6 you'll not have the one vehicle between you?
I've ridden this solo tons of times and while I don't mind filling in spaces on other stuff, there's no way I'm sharing my ride vehicle on the peoplemover with anyone but my party. So I really hope it's just poorly written.
