Just like a regular hotel, a cruise ship is staffed with a Hotel Manager, Chief Purser, and Chief Steward. Which of the following is a position not found in a hotel environment?

The position of Captain is specifically unique to a maritime environment like a cruise ship, as it refers to the individual responsible for the overall operation and safety of the vessel at sea. The Captain's role encompasses navigation, managing the crew, and ensuring passenger safety, which are duties that do not exist in a traditional hotel setting.

In contrast, the other roles mentioned, such as Housekeeping Manager, Director of Sales, and Event Coordinator, are all integral to hotel operations. These positions focus on managing guest services, overseeing room cleanliness, organizing events, and driving sales, all of which are essential functions in a hotel but do not translate to a cruise ship environment in the same way. The cruise ship does have similar roles that might function differently, but the specific title of Captain remains exclusive to maritime operations.
