On Royal Caribbean, "Category C" historically refers to a specific sub-classification of Ocean View Staterooms, though the exact nomenclature can vary slightly depending on the age and class of the ship. Typically, a Category C room is a Large Ocean View cabin. These staterooms feature a large, non-opening window (porthole or picture window) that allows natural light into the room and provides a view of the sea, but they do not have a private balcony. In terms of size, they are generally roomier than standard interior cabins, often ranging from 170 to 210 square feet. On older ships like the Vision or Radiance class, Category C might represent one of the "best" non-suite ocean view locations, often situated on middle decks with unobstructed views. In 2026, Royal Caribbean has shifted toward more descriptive names like "Spacious Ocean View," but you will still see the alphanumeric codes in technical deck plans. Choosing this category is a popular "middle ground" for travelers who want to avoid the claustrophobia of an inside room but don't want to pay the significant price premium required for a balcony or suite.
