Replying to Should i tell the folks?

So last night was st. patricks day, and of course the only right thing to do if you're irish is to drink. well my band played a show at a buddy's party and then we all chilled and drank. but of course the cops show up and issue roughly 30 consumption/possesion tickets, me included. now i'm 18 so i'm considered an adult and don't need my parents to be present at my court hearing, so i dont have to tell them anything. i don't know though if i should just go ahead and tell them what happened and face it, or keep it quiet and hope court goes good and i get off free. i need some help..
