Yes, you do around 7a

Show up around 7 or 8 mon-thurs, you would be okay...thx

Went there on a monday evening and there wasn't even a line

Yes. The QR code gets change every day. If you scan it and your number is anywhere under 314. Chances are you will be able to go in at 1230 pm approximately

I scanned mine at around 11:00 and got in around 3:00.

Yes you have to be there at 7:00am in the morning to have the code scan in the Harry potter stores in New York city
