Virtual line!

[Yano]

Can someone please explain to me how the virtual line works? And do I need to use it if I have unlimited Express pass?
Thank you

Well with the Fallon ride, when you enter the building you’re given a card with a certain color. When the lights on the room turn your color you go upstairs and you can lounge in the AC until the lights on that room turn your color then you ride. So much better than waiting in cattle pens standing.
