Very good advice here. Thank you!
Specifically, I would like to be able to discuss with him how to get in touch with us if he is in Edge and wants/needs to leave. Do cell phones work? (Sorry if that's a silly question, but there is so much I don't know!)
What are our options if we are out on an excursion and something puts him into defense mode or he just needs a quiet time out?
I'm hoping there might be other HFA kids that may be on the same cruise who he could "hang out" with.
Food is not really an issue, thank goodness. However, he is also hearing impaired. I'd like to be able to offer him as much freedom as possible (although he is just beginning to want to do things alone or just with friends), while feeling as confident as possible that he is safe.
