Although, your answer is correct, for as far as it goes, the just of the question is one that I wonder about as well. If I were prone to skin cancer so severe that I have to stay out of the sun as much as possible, number one, I would not go to the Sunshine State for any reason if being there made me spend uncontrollable times in the sun regardless of precautions taken. Would I like to go, yes, but, I would have a physical problem that says that I cannot experience it. It's not a shame to not be able to do stuff, it is, however, not reasonable to expect everyone to move heaven and earth to accommodate you. You are responsible for your own health and if you are foolish enough to trust a unknown third party to protect you...you might be in trouble.
If you cannot handle heat, then Florida in the summer is not the place for you. You might want to be there, but, you, not someone else, is putting your health and possibly your life at risk to go there. Is it worth it? I don't see how.
If you have a child that panics when in crowds or cannot wait in a line or cannot handle high activity or loud noises, you may want them to experience what you find as a wonderful time at a Disney Park, however, I fail to see how it is a wonderful time for them. You may be having a good time, but, you're not suffering from anxiety, they are. You may justify it because of that one precious moment when the child responds positively to the environment, but it is a fleeting moment and the rest of the time they are miserable. I almost see that as cruel and not loving at all. I don't think that I would ever have wanted to subject my child to that kind of stress if I could avoid it. That would be something that would have to wait until they could handle it. I would never have thought that others, that are unrelated and not directly connected to them should be asked to sacrifice their enjoyment to accommodate someone that didn't really have to be there. I will stand aside all day long for a Make-a-Wish child, because they may not have a tomorrow to work with. Others, in my mind, have to weigh their actual need against their desire balanced on the degree of the problem and the amount that others have to be affected in order to make that happen.
