Your best bet would be to talk with the camp counselor onboard. Also try the shore excursion staffer. They can help you out because they are more aware of any problems that your child might encounter or this (past) cruise or future cruises. Hope that all of you enjoy cruising in the future also.
I would vote for any tactile events. Such as swimming with Dolphins, Manta Rays etc.
This gets the child in the water, which can be comforting, and gentle creatures always bring smiles.
Give it a thought.
