On a 2026 cruise ship deck plan, a triangle symbol (▲) typically indicates that the stateroom has a third berth, usually in the form of a "pullman" bed that drops from the ceiling or a single sofa bed. This is a crucial detail for families or groups of three traveling together. If the triangle is inverted (▼), some lines use it to denote an accessible cabin with wider doorways and a roll-in shower, though this varies by carrier. It is important to distinguish the triangle from other symbols like a plus sign (+) for four-person rooms or a star (*) for interconnecting doors. In 2026, as ships become more specialized, you might also see a "partial triangle" indicating a partially obstructed view on some older vessels. Always consult the specific "Deck Plan Legend" for your ship in the 2026 cruise app, as these symbols are the "secret code" that ensures you don't accidentally book a room that can't accommodate your entire party.
