I dont understand. You seem to be contradicting yourself, but maybe I'm just reading it wrong.
Here it seems like you are saying that if you want your friend (who isn't getting an autograph) to take your photo then they must have a virtual ticket, but then you say
Can you please clarify it?
Also, will the guests be signing from when the doors open? I'm asking this because if I were to be first in the Val Kilmer queue, for example, and he wasn't already there when the doors had opened and I went to his area, I could be standing in the queue for a number of minutes during which no virtual queueing tickets were being issued (thus being able to have my photo taken with him) and then tickets started being handed out just before he arrived. I would find this very unfair. I for one, as well as a number of others I know, only like meeting guests if I get a photo with them, and if the above happened I would be extremely upset.
Surely there should be an option avaliable to get both a photo and a personalisation (perhaps with no/limited conversation) without holding the queue?
An idea for this is to have stewards writing on post-it notes after you have paid for your autographs but before you reach the table. They could write, for example, "To XXX plus photo", so the guest could personalise it straight away, then turn around for a quick snapshot. It would waste no time at all (or possibly 2 seconds for the photo).
