[Callers] Dances for special needs folks at a public dance

Hi, I am preparing for a public dance series where special needs folks, folks with some learning disabilities, have been present in the past. I have my share of easy dances but I am wondering if any of you have experience with the special needs of special needs dancers. One of these dancers has been described to me as on the autistic spectrum. Do you have experience teaching such dancers? Were there approaches that worked well, or otherwise good teaching that in this situation did not work well? Are there dances you would suggest? Have you found that dances that keep dancers physically connected are any better than those that do so less? Your help in giving as many dancers a good time as possible will be appreciated by all. Thanks, Rickey Holt P.S. The rest of the dancers at this series are already used to easy dances.
