Recently back from my first trip with mobility issues; it was much easier than I imagined and boosted my self confidence.
Rented from an offsite vendor to have the scooter from hotel check into check out which would not be the case if renting from Disney. Disney rentals are only from park to park, basically with no coverage in between. Used Gold Mobility and found them conscientious, timely and knowledgeable.
I do not drive thus found a longggg learning curve

. Biggest problem was getting on and off buses and I learned to admit to needing help from the bus operators. My trip only lasted 5 days but by the midpoint I was able to get on and off the bus solo as long as no backwards maneuvering was required.
The average pedestrian is engrossed in their personal bubble so neither horn honking or “Helloooo…” will get their immediate attention so you must be more aware of them than they will be of you.
Should you use a tri or quad cane it will not fit in the given accessory for carrying a cane. This will mean you will need to drive to your table with less moving space than normal. You may want to purchase a cane carrier to increase your independent mobility.
I was impressed with the accessories that were included with my rental: cell phone carrier that attached to the console (invaluable and will purchase same for personal use), cup holder (never used but well placed), cane holder (see above) and disposable rain ponchos. I found the front basket was enough to hold my gear with the running board but was always a minimalist before my stroke; YMMV and an additional rear basket maybe of use. Having read this forum before my vac, I used the hotel shower cap to protect the console and it did a fine job w/o extra material flapping in the wind. Personally, I found the 3 wheel scooters easier to navigate than the 4 wheelers; turning mechanism (radius?) is tighter.
All and all, found using the scooter much more freeing than anticipated and am in fact in the middle of researching a purchase of my own for the next trip.
Not asked but I’m volunteering info so the most annoying part of this trip was navigating the airport. No, not driving just dealing with the bureaucracy. After assurances that someone would meet me terminal curbside didn’t happen and my traveling companion and I had to make it with luggage and manual wheelchair to the not opened yet airline desk. We were fortunate that other early passengers took pity on us but I will never allow myself to be in a similar predicament again. Great when an attendant came on duty 1-1/2 hours
after my airport arrival but well I do despise depending on others so there is that.
Have fun and hope you enjoy yourself.
