DW and I are both ECV users. She has her own but I rent one.
The handicapped parking area is too far from where I had to go to rent an ECV. I managed to do the walk in the morning, with great effort. Upon leaving, I just knew that I could not handle that long walk again. The rental place would not allow me to take the ECV back to the parking area, but they did offer a manual wheelchair, which may have worked if I had some one else to push me. I had to go to guest relations office to complain. There, they arranged for a van to pick me up and drive me to my car.
It looks like Universal is now off limits to me.
