Holidays for young adults with autism

Hi

I am the mother of a young man wild mild autism and a language disorder. He is 22 years old, and has recently got a full time job which he is really enjoying! (I am very proud of him :))

He has told me he woud like to go on holiday. He doesn't really have friends he can go with and I can understand that he would rather not go with his mother! So he would be going alone.

Does anyone have any recommendations of companies/organisations that offer supported holidays that he could go on? He would prefer physical doing-things type holidays with people his own age or near.

Any help gratefuly welcomed. Especially if you have personal experience of these holidays.

Thank you very much.
