Two Saturday tickets needed, want to take our 5-year-old daughters

I got the camping tickets but somehow didn’t get two festival tickets for Saturday. My friend and I were planning on taking our 5-year-old daughters. We have camping tickets at Laverne. We will return them if we can’t get tickets to the show. Please help me, I am so sad. The vehicle spots were sold out by the time I was able to get in, so I am looking for that too. Thank you for your help!!!
