On a cruise ship, "BB" typically refers to a specific grade of Balcony Cabin. Most cruise lines (such as Princess or MSC) use a two-letter coding system to categorize rooms based on their location and perks. A "B" code signifies a balcony, and the second "B" denotes its sub-category or "rank." Generally, a BB cabin is in a "mid-tier" location—often on a higher deck or closer to the middle of the ship than a BC or BD cabin, but perhaps not as perfectly centered as a BA cabin. The interior of the room is usually identical to other balcony cabins, so you are essentially paying for a better "position" on the ship. Occasionally, "BB" can also refer to "Bed and Breakfast" in a meal plan context (rare on major lines but common on European river cruises), indicating that only your morning meal is included in the fare, while lunch and dinner are extra.
