I have looked around the convention but I haven't found any of the other QR codes. I don't want to be told where they are but just a clue. Are they on the walls of the booths? Hidden in out of the way places that you'd miss on first glance? I have looked quite thoroughly but I don't know where else to look.

There's a few in booths. They may be on the walls, or on something in the booth. One was in a little plastic stand, perhaps A5 in size but the rest were an A4 sheet.

Some of the ones in the booths can be tricky to see if your not looking for them. but the rest should be pretty easy to find.
