My DH is a type one diabetic do we have had extensive experience with the first aid center storing insulin which needs to be kept cold. We have never had a problem as it is easy access to the meds when you need them. The only problem we have had is you need to pick up your meds at least half an hour before the park closses and usually more time than that. We showed up about and hour before the fireworks one night and they had already shut up for the night. This is not usual, but did happen to us. Lucky for us we had more in our room and picked up the other supply in the morning which required and extra trip into the park and altered plans.
