convention center

Hello maespura vida, I need help 😭 I have a concert coming up at the convention center soon and I need to get there early to get a good view. The problem is, I don't know the convention center at all. I don't know where to wait until the doors open. I plan to arrive very early and I really don't want to be disoriented 😭 Please share with me your experiences at the convention center for a concert or something like that you experienced, thank you very much 🥹🥹🥹
