I think you are missing the point entirely. Assuming that you can provide solutions for other people is never a good idea. Unless you have been in their shoes and know exactly their specific needs, solutions and ideas will always fall short in one way or another. Everyone needs to determine what is right for their own families, and for their own peace of mind. It doesn't matter how many backups for backups for backups someone might have, there will always be a situation that can't possibly be planned for or foreseen.
I think the point that is trying to be made by some of the comments in this thread is that while the policy may be wonderful for the majority of guests, there ought to be reasonable exceptions, as there are in other parts of the park via the GAC, for those people who may find it difficult to manage. While there are ways to avoid this specific policy now, there may not be any way to avoid it in the future should it be expanded, and the time to voice an opinion on it is before it's too late and those changes as been made. By definition "reasonable exception" is not "bending over backwards".
I am not pointing fingers, or even specifically responding to the opinions or comments stated in this thread, but there is, in general, a lot of subtle and even open hostility between people with differing opinions, and special needs, even within the community itself, is a hotbed of this.
