Hello! My 9 year old son is on the spectrum and qualifies for DAS at WDW. We do a lot of priming expectations and preparing him for waiting and crowds when we are in the Parks. I've never been on a cruise before so I am wondering if there are accommodations I can make for him to make it more enjoyable. I've been researching for months but any first hand advice or tips would be appreciated!
