Disgraceful! I received that link earlier today. I don't want to turn this into an issue about how different countries treat disabled children because, hopefully, this was about terrible staff and managers acting on bad policy, but a few years ago we had a similar experience that made my family recoil in horror. We were on holiday in Majorca, on a large hotel complex on the beach, 10 of us including a 13 year old child with learnng disabilities who can walk a little but needs a wheelchair as her coordination is affected.
We went each evening to the open air enterainment, and in the middle of our holiday, we took the children to their show before bedtime, where there was disco dancing. The 13 year old loved music and liked to get up with her dad, who would dance around her doing silly dad moves to make her laugh. She was obviously much older than the other children, and few teenagers wanted to join in. A very angry German woman walked over to dad and berated him in fluent English for bringing his daughter out and 'displaying' her to the public. He felt humiliated and was in tears. As he walked away without attempting to explain anything to her, she called him a stupid Englishman with no understanding about sick children. Another member of our party went to speak quietly to her, but she was adamant that you should not 'lark about' with a disabled child, and we were equally adamant that she had misunderstood what she saw, but she wasn't having it, nor were her adult companions.
Of course disabled children should be protected and cherished, and enabled to join in as much as they can, including being priortised for seats and being helped to dance and have fun.
