Going to a concert next week and the parking passes are sold out. Does anyone know good and safe place to park? Preferable free but if it's paid idc as long as it's safe. Thx

I've been here before but I was wondering if other people can answer my question. Next year I want to see 2 groups but they're playing on the same day. One at 7pm downstairs and the other 8pm upstairs. What I want to know if do I still have to buy a ticket for both even if it's still in the same building? And also would it be one band then the other? As in one group finishes then the other comes in or multiple groups can play at the same time. I wanna see both but I'm not trying to race up and downstairs. Thx
