Trouble getting Apple watch "try-on" appointment for Apple Watch Series 4

I learned yesterday when visiting an Apple store that the demo watches don't allow anyone to test the watch's accessibility features.

I am interested in possibly buying a watch for my adult daughter who is blind and has some developmental delay. She uses her iPhone 6 and its accessibility features pretty well. But because she has some minor hand coordination limitations, it's important for her to see if she can handle gestures on a smaller watch screen. She has never used an Apple watch before.

After our unsuccessful visit yesterday, I researched the internet and found an AppleVis Blog post back in 2015, updated in 2017, noting that Apple was letting people who are blind or visually impaired make an Apple Watch "try-on" appointment at an Apple store to test out accessibility features.

I tried to set up a "try-on" appointment using the procedure described in the past AppleVis Blog post- all to no avail. The Apple reps both on the telephone and in another Apple store said they were not making any such "try on" appointments, and I had two choices: (1) buy the watch and wait until January 2019 to take a class at the store, or (2) buy the watch, try out its accessibility features at home, and return it within 2 weeks if it didn't work out.

Has anyone else had any recent success with getting a "try on" appointment? Thank you.
