If it was Belgium a few months ago, my apologies, it was me.😊
We took off in Ds's car at 4 am, and made it to the port before I realized I'd left it behind.
I was able to put my badge number on the note.
But most took one look at me in a wheelchair with attached devices, doing my level best at independence, in a situation and country not that well geared up for me, and where really kind, understanding and helpful, from the ship to the hotel, and the lovely Brugge parking warden who insisted Ds shouldn't drop me in the street and go hunt for a space, and put his ID no on DS's car to say it was OK...
Except for the British family at the hotel, who insisted that as they had their badge they should take priority even though they didn't actually need a disabled hotel car park space, just a guaranteed car park space. (which we all had)
The hotel told them I'd had to pay extra for a a disabled room with hoist, and the space came with it, and where really shocked as they could see that I simply couldn't get in and out in in a standard space. Even after, for the sake of peace, Ds went for dropping me at the front, parking in a standard space, and then coming and getting me later to get me in, they couldn't believe the way the family kicked off about how I might be pretending to be disabled, after they publicly confronted me at breakfast despite being told I'd had to pay extra for a wheelchair accessible room.
Their anger marred their break more than mine, though I found myself having to apologize for their behavior towards me to the staff and shocked guests, who couldn't believe I was sanguine about their attitude because of UK attitudes towards disabled people.
Sadly I simply can't "stand on this issue" - hence the wheelchair.
Your dad's attitude will shave years off his life, your mum probably knows.
