Honestly just go in comfy shoes and be prepared to stand for basically the whole time. Our whole stadium was on their feet for the ENTIRE show. It was a once in a lifetime experience. If you go with the intent to have fun and just live in the moment, you’ll have a great time!
I also made and traded friendship bracelets, which was an amazing experience. I now have bracelets from other people that I can display as part of my concert memories, which I love.
I have student prime and it only costs me $40CAD/year for prime music, video, and shipping. It’s way cheaper than literally any other streaming service I have.
