I largely agree with you
My main complaint with VQ with MoM were the IT failures. The button didn't always appear at the time it was supposed to (it could appear early or late), and more than likely it would give you an error message.
I'd prefer the system to work more like Volcano Bay, where you have to go up to the MoM line and check in, with each individual person, then given a return time based on how many other people have checked in before you. Then once it fills up, they mark it as "at capacity."
