Concert tips?

Hi! so for background info I'm 19 F, and I have pots. I have had bad symptoms for like 2 years now but I am only recently diagnosed. I am supposed to go to warped tour in Florida, in November. I am very excited but I am also worried about how I will even be able to survive it. I probably normally wouldn't go because of my pots and the heat and walking but i was gifted the ticket and i really want to go so im trying to push myself. I was wondering if anyone had any tips or products that would help me out. I already have a fitbit that I use that tracks my heart rate and everything and I am prepared to drink so much Gatorade. Does anyone have any good concert advice? Or any cheaper products maybe that could assist me?
