Prepare For Motion Sickness
You might not be aware of your sensitivity to motion until it’s too late. But if you are aware, then loading your carry on with motion sickness medication like Dramamine is a great idea. A fun tidbit is that the higher the cabin you sleep in, the less likely you are to get motion sickness while you’re in the cabin. All bets are off when you’re on the ship deck, though—every person for themselves.
