Okay, so I have a friend who is going to be out of town for the first two days of con but wants to attend for the last day. However, the problem is she doesn't have any ID. She doesn't have a drivers license or a current passport and can't find her school ID (and ours don't list birth dates anyways, so as I understand it those wouldn't work). Is there anything else she can use? Alternatively, since she's sixteen, would it be okay for one of her parents to go with her and show their ID instead?
Somewhat related to the above, is it necessary to have birth date listed on whatever ID we use if we're under eighteen? I have a current passport I can use, but if something without birth date is acceptable, I'd rather bring my school ID, since it's less valuable and easier to replace if it gets lost or stolen.
