It doesn't defeat the purpose. I've read that they force you to wait in a separate area anyway with rider switch which is hardly a great way to spend time. The whole point is that you all get to go on the ride, and don't have to q twice. Being forced to wait separately in a room for an hour or longer is as bad as qing if not worse. Why they can't just split you just before you go on the ride I don't know. Sounds like a ridiculously overengineered process
