The cost is somewhat irrelevant if you CANNOT experience the parks without reasonable accommodation. Without the
DAS, we cannot do Disney. So it becomes one of many decision pricing points.
In any event, as soon as we saw this news (we are Uni AP holders with 2 trips planned), we reached out to my DAS holder's doctor (who was the one who told us about the pass and pretty much said we needed it or the parks wouldn't work for us anymore). Her doctor is on maternity leave, so her "stand-in" responded via MyChart the same day. We have regular 6 month appointments required/recommended; and so at the next appointment in 2 weeks the letter will be provided.
The problem we saw was that for the initial online registration, our specific condition is not one of the "choices" so not sure how that will work?
