Study materials about "How to help the disabled client on holiday" by Lucia van Kruijl

I would like to ask all the members if someone has study-material for giving courses "how to help the disabled client on holiday".

What's made for touristic- and hotel-educations/schools?

Maybe someone can help me with that?
