Diabetics?

Hey everyone, we are looking into going to this festival this year. I have never been to a festival that doesn’t allow reentry and this is a bit of a concern as I have a insulin pump. Have the Omnipod five and if you have one, you know, sometimes you run out early because you’re either eating more, or drinking more. my fear is that I am going to run out of insulin in my pod and need to switch it and not be able to go back to our hotel or car. Has anybody run into this and do they make exceptions for medical things? I also am not willing to bring a vial of insulin, as if it’s out in the hot sun all day it will ruin it and waste the rest of the bottle. I wasn’t sure if anybody had any experience with the medical tent and if they’re willing to store it in a refrigerator or anything but any advice would be awesome. Thanks!!
