1st time event?

Hihi I saw tickets online for her concert in NY for around $125? Thing is, I’ve never been to a concert before, and I’d be going alone. Do you think it’d be worth going? The tickets I’m eyeing are in rows GA2 n GA3, would those be good seats? I fr know nothing abt concerts :( I’m just nervous, idm paying money but I’d prob have to get a hotel too since it’s so late n I’d be going by train / subway etc etc. Thanks in advance!!
