What do you pack in your carry on??

[vleeth]

We'll be driving. So I'm thinking we'll have a "carryon" for the car trip that we leave in the car and another carryon to take on the ship. And I'll have her put her bathing suit on before we board. So I'm sure that will cut down on how much stuff she has to carry around the ship.

Other than sunscreen, her camera and a light sweater for inside, I can't think of what else she would need in her bag. Am I missing something?
