Kids at Coachella?

Do you think it would be ok for a 13 year old girl, her 16 year old cousin, and her 19 year old brother to go to coachella? Or is 13 too young? I’ve been reading a lot of articles about parents bringing their younger children to Coachella. I think it’s okay if she’s with her brother and cousin there to protect her (including some friends 18-19), she’s a good kid and wants to see some of her favorite singers.

I just need some other people’s opinions please:)

And if she does go what should i make her bring?
