Books that take place on cruises or all inclusives

I'm going on a cruise soon and super excited!

Looking for vacation/cruise/boat related novels. Doesn't necessarily have to be a cruise but beach, resort, yachts, etc in general are all good

I've read the Woman in Cabin 10, so anything but that. I love horror/thriller/mystery books and romance/romcoms.

Something relatively short (300ish pages) would be preferred.
