Nah, the QR code is just a 'shorthand' way to tell your browser 'go to this website'. No scavenger hunt needed
Go to the site now and set up an account, then try to book a VQ. It won't work if you aren't in the geo fence, but will give you an idea of how the booking works and serve as a practice run. That will put you miles ahead of the average park guest who hasn't heard about this new way to book VQs.
ETA: So maybe not right NOW, because the park is closed and it won't let you even try to reserve. Try it some time tomorrow when the park is open.
