I live in Scotland so things might be different here. It’s also some time since I got a blue badge for my late husband. When i applied i emphasised the need to be able to park near disabled toilets, not being able to leave him anywhere near where we wanted to be while I looked for a parking space, the fact that I difficulty getting him out of the car so the wider disabled parking spaces were need for me to be able to manipulate him out of the car.
Not sure if any of that is any help. Good luck.
