A cruise ship is a self-contained world at sea — and working on one means using English across every aspect of hospitality simultaneously: accommodation, dining, entertainment, excursions, retail, and a full range of guest services, all delivered to people from dozens of countries over a voyage that can last weeks. The vocabulary in this exercise covers the English that cruise ship workers use most in their early interactions with guests: the language of embarkation, cabin orientation, onboard services, and the specific terms of cruise life that passengers use fluently and expect crew to match. Getting this vocabulary right makes the difference between a guest who feels at home on board and one who spends the whole voyage slightly confused.
