I have no experience or knowledge of your friends condition and how things may go for her there. But from my experience I had no issues with getting a
DAS and a stroller tagged as a wheelchair for my son in CA. The woman I dealt with was great and barely wanted to know anything about our needs (but they are a more common one) and offered to tag the stroller for us before I had a chance to ask. We were there later on our arrival day (maybe 3:30 or 4pm) and it was a very smooth, quick and painless process.
