Looking for your help. I'm planning to offer respite for parents during the school holidays

I am a tutor for children with autism and those with SEMH problems. I am planning to offer respite for parents during the school holidays and thought here would be a great place to find out what people need, your good and bad experiences that I can learn from and people's expectations. I feel I know a lot of this through my own experience but you can never know it all !! Also if appropriate I would like to know how much people pay/charge . Thank you K
