there’s an upcoming show in March, the venue says 16+, if I were to bring a guardian that was 16+, can I get in, if I’m not?

where you allowed in? because I have the same issue

Should just call, sometimes that's allowable because only those who drink get stamped or are issued a wristband.

I would think so but call them to confirm.

I don't believe so. You need your own ID to get in if you are a minor.
