Social stories / advice for cruise holidays

Hello, has anyone been on a cruise recently that has a good social story they’re willing to share with me please? This is our first time on a cruise and I’ve no idea what to expect, so I wouldn’t know where to start in creating a social story for my 4 year old autistic boy. 

Alternatively, if anyone has any advice on how to prepare and what to expect in a cruise, that would be much appreciated. We’re visiting the Norwegian Fjords in June.
