I do recall that, someone on twitter who ran a charity for people who had lost limbs wrote a post about being invited to send someone from their charity to the games, think it was the Canada games, they declined after realizing how much it was going to cost their charity, she listed all the expenses they were expected to cover, flights, accommodation, expenses for 5 people, 2 participants, coach, trainer and Physio, I think. Travel insurance. Families having to self pay their own travel expenses. And she was particularly angry about the NDA’s they were required to sign if they chose to participate.
I remember it being discussed on here at the time.
