Hi, !
I can't offer much more than the input Richard offered, but I hope your family is on board and supportive. Please know I know this is not the same, but my Aunt had to start using a walker as her Parkinson's has progressed. She fought it tooth and nail, but now that she's using it, it has actually given her more freedom and confidence. She still occasionally seems to worry about putting people out or what others might think, but I hope as time goes on, she can quiet those thoughts.
And, from her family's perspective? Oh, boy. It's kind of a relief. We love being able to include her in pretty much everything and to not have to stress about her falling, figuring out how she will navigate stairs and such. Mind you, this is all in the US and I know some countries just don't have the same ADA standards (one, because the ADA is specifically American and I realize that and two, you can only adapt ancient castles and cobblestone streets to a point). I do think most areas used to cruise traffic will have some accessibility accommodations, if you are cruising outside of the US.
And, selfishly? We have liked the extra storage her walker has and that we occasionally get the VIP treatment (access to elevators, shorter wait times, etc). I know that doesn't make up for the challenges of navigating activities with a wheelchair (or walker) and please know I am not making light of your (or my aunt's) situation.
But. If any of my words or Richard's help stop the spiral, then mission accomplished. I hope you have a WONDERFUL time and that your energy reserves can be spent having fun and making great memories!
Best, Erin, Team Member.
