@jmb73 what a fun trip you have planned! We have been to both Dublin and Milan but I was younger then! You may want to check with the hotel in advance to see if they have tour guides with cars. Walking on crowded streets with cobblestones can be very difficult also ask about stairs. My observation of Europe was that there was no accommodation for the disabled. The cities are old and built before any modern conveniences. If the old parts of the cities were changed to today’s modern standards, they would lose their history and charm. I don’t want to discourage you, but you will need to do your homework!
