The cost of a Carnival cruise room upgrade depends on the difference between your original stateroom and the higher-category cabin you want. Moving from an interior room to an ocean-view cabin, balcony room, or suite may involve a different additional fare. Prices also vary according to the ship, sailing date, cabin location, and remaining availability. Carnival does not publish one fixed upgrade price for every cruise, so you should request a personalized quote before making changes.
