First concert!!

So the day the world tour vip tickets went in sale, I was somehow I managed to snag one of them, but as the countdown begins, I had a question or 2. Im autistic with a sensory issues essentially to loud sounds and this is not only my first ghost concert but my first concert period (unless you count school band concerts I had to play in but I dont). I should be fine with my ear protectors, but I wanted to know what else I should expect??

Also, I've been seeing all over socials, Kandi bracelets trading is a big thing in alt concerts?? Is that really something I should expect/prepare for? Any input would be appreciated . Thank you so much for reading.
