First thing, if I were to go again, I would purchase a euro key so I could use the disabled public restrooms. Most of them in town squares and at highway rest stops were locked throughout Germany and Austria and you couldn’t use them unless you have the euro key, Or were lucky enough to be there when someone else had the door unlocked.
Chain hotels were pretty good about having wheelchair accessible rooms as advertised. I had good luck with Holiday Inn, Park Inn and Motel One. I was disappointed with Best Western in Vösendorf, Austria, Their “wheelchair accessible” room had zero grab bars which was very difficult in the bathroom. I had to use a wooden chair for extra transfer support. Plus, they had a bath tub with a half wall instead of a curtain, also no grab bars.
Public transit was great. Drivers usually had to come out and set out a manual ramp on buses and trains. I had one major problem on the tram from Vösendorf to Vienna. When exiting, the tram operator told me the lift was all the way down and ready for me to roll. My friend confirmed it was OK and they both were looking from the inside of the tram. It was really still eight inches above grade. I ended up rolling off onto my face and breaking my nose. He apologized profusely and I was taken by ambulance to a hospital. It all is healing, tram folks are investigating. I now understand why lifts are operated from the outside where I live in America. Next time I’m sending my able-bodied friend out first!
Beware of Austria’s toll road policy! When we were in Austria, we could not find an open, manned booth or automatic place to pay tolls. It turns out we were supposed to have registered online or bought a pass (where?) and registered that way. Instead of a 10-day pass for 8 euros, we are paying a €240 fine! Here is a website to register online. I have not used it so I don’t know personally how it works. https://vignette-sofort.at/en/Index/
