I never envisioned me asking this question. Walking is a hobby of mine and something I did dailly for 5 miles easily at a clip. A knee surgery derailed me in the fall. I have physically recovered but am left with a biomechanical issue now where my knee bones want to rotate out despite PT, chiro adjustments, etc. I can walk around a mall fine, downtown disney will be fine, the hotel will be fine...I just can't wrap my head around Epcot and DHS, my two park choices this summer. If i walk TOO much my knee aches, swells a little and just numbs...Is there a difference between scooter and ECV? We will have a split stay between POFQ and YC CL. If I rent from apple where do I park the chair at night? Is it a hassle to navigate in one? Any advice is so appreciated...
