A side note here. We are driving to all parks except MK. This is a first for us. If I didn't have to use an ECV, I wouldn't do it. Parking and walking to the tram stop and having to ride it in isn't fun.
But last year we had a hard time finding space on the buses for me. One day we waited 1.5 hours for an EPCOT bus.
I got a disability tag from my doctor for this trip. We are able to park in the disability lot which is just a few rows from the entrance.
Every morning I take a pain pill and apply a lidocaine patch to my lower back. I'm able to make it through the day, but by dinnertime I'm in a lot of pain and can barely walk. And I crash shortly after because I'm just not up to evening activities.
