AFI SEP.19 at Santa ana observatory

Hi all. I have a question about the upcoming show this Saturday. I have 3 tickets but one person has bailed for this show so I'm considering taking my 16 year old. I have called and looked online whether this specific event is age restricted but can't find anything and would like to be sure before we drive out from SD with her. I called twice but can't seem to get any info and on the ticket page I can't seem to see anything either.

Any help would be appreciated!
