Don't read this wrong, but, it seems to me that the Braille maps are there more for show then anything else. The parks are 90% visual. I don't think I have ever seen a completely blind person there over all those years. The only attraction that they had that would have fit in was "Sounds Dangerous" and that closed a long time ago. If a person did go that had vision restrictions to the point of needing braille, would they be by themselves or would they have someone with them? They don't know the parks, they don't know how to get their bearings without that experience. That leads me to the conclusion that they have put up Braille maps just so someone would say... oh, look they have done something to help a person with a vision challenge. Highly doubtful that it would be in very high demand, especially in light of the fact it has not been upgraded for this long.
Just to head this off at the pass, yes, I know that many with varying degrees of impaired vision probably do go to the parks. However, the same thing applies, it is not likely that they would be going there by themselves with no visually strong individual to help identify and clarify what is happening. Realistically, it seems to me that a huge amount of the magic would be lost without strong visual enforcement.
