I know this is in the logistics “grey area”; but, I think express is set to run a little differently (if that article is to be believed...and it’s all we have to go on at this point).
It sounds like VQ will be designed to spread out and schedule express throughout the night.
So, let’s say that the same 100 people all enter at the same time. 50 express people say that they have BJ on their list. Those 50 get scheduled for a virtual queue from entrance time throughout the night. Let’s say that 15 get scheduled right away.
Assuming the house/queue holds 40, that means that 25 non-express can get into the queue right away.
Again, this is still some rough math, and there are still a lot of assumptions. But, that’s how I pictured it happening after reading that article. And yes, that also means that non-expressers can get locked out if they have bad timing.
