I have had *years* of PT - all aimed at keeping me up, on my feet, mobile, using the minimal amount of assistive devices possible.
At WDW, all of that is out the window.
First of all, the *average* Guest walks between 3 &10 mile *per day*. How far can you walk unassisted before it takes a serious toll on you?
Then let's talk about pain management. As in, if you don't stay
ahead of your pain, and you get into what my PT calls a "pain spiral", you can ruin your entire trip to WDW before breakfast on the second day.
And last but not least, how does it benefit you to (potentially) wind up back at physical therapy after Disney World, because you didn't want to use the best available tool? (which in this case is an ECV).
Sometimes we have to do things we don't want to, right? Everyone has had that experience. And using an ECV (or whatever mobility device or assistance is appropriate for you) falls into that category. You are still at Disney World, even if you have to use a scooter - you are still where *thousands* of other people wish and dream and pray to be every single day.
