I'm going to the concert soon, it'll be my first one too so I'm really nervous and barely know what I'm doing. My ticket says "Kein Sitzanspruch" which basically means no guaranteed seat, but I also got a seat number? So I'm kinda confused. I'm guessing its a suggestion but I'd still like to know! Do I have to go to that seat even when I'm early? (Since mine is way back) Thank you!

Small edit with extra question: I'm using the disability entrance that the venue offers, does anyone know if I'll still get in there good if I arrive close to when the doors open?
