Wow. You have a lot to think through here. I’m so sorry for your dear wife (& you too)!! But it seems like you both have a great attitude and mindset going into this trip, and I hope it’s a huge blessing for you all!!
I think AKV is going to be the best place to be on this particular trip- quiet, relaxing, beautiful, and transportive.

Bay Lake, however, may have a few issues (noise-wise)… you can hear MK’s fireworks from
inside many of the rooms (so I would make sure to talk with the front desk about getting the quietest room possible), and at both resorts I would make sure your room isn’t too close to the pools (the games and music can get pretty loud too).
I think Epcot & the Boardwalk area have several little nooks/quiet places to sit back and relax (like Mamabunny said

). Animal Kingdom is probably the quietest park though (especially the animal trails!), and could be a wonderful diversion.
For me, it’s easier to think of things I would
avoid… like the buses. As soon as a wheelchair user needs to board (like myself), the bus makes a horridly loud beeping noise as it “kneels” to the curb & drops the ramp (& then back up again!). That right there could end your wife’s day before it even has a chance to start. I think you’re driving (right?), but be aware of the buses around you… and I would definitely plan to rent a push WC for her
(just make sure that you pay attention to the road’s surface you are driving her on, bc there are areas in every park that are “themed” that make it bumpy & she would probably do better walking over that than being jostled).
I would grab a guide map as you enter each park (or at your resort beforehand) & try to make notes of times/places to
avoid… especially at Epcot (it has lots of quiet places, but also some of the loudest entertainment on property)! The America Gardens Theatre is made to project sound, and my son (who gets sound-induced migraines) cannot tolerate being within a few
countries of that theatre when there are any instruments playing (it was especially hard during Covid when they used the AG theatre for Mexico & Canada’s bands). There are some pretty loud acts which are beginning to play in their own countries again (like Japan), and whenever cavalcades come around the music is turned way up on nearby speakers (that goes for MK, EP & HS). At AK, there are some loud “street performers” to be aware of (esp. in Africa). And at MK, the Liberty Belle steamboat (which cruises on the hour & half hour), has a very loud “horn” that is used whenever it approaches & exits the dock. I’m sure I’m missing something, but these are the things I watch out for with my son (he also keeps Bose noise-cancelling headphones in his backpack, so he can quickly put them on to keep from getting sick… side note- I would not recommend his headphones to your wife as they can create an uncomfortable suction feeling & pressure to the head; the noise-canceling earplugs seem better). Obviously, nighttime fireworks are going to be very loud & visually dynamic shows too (both inside & nearby those parks), so I’d avoid those as well.
That may seem like a lot to be “on alert” for, but the really good news is that Disney is finally putting all cavalcades & showtimes in the daily guide maps! No more pop-ups!! No more guessing!!!


I truly wish you the best & hope you make some wonderful memories on this trip!!
