What is the role of a night porter in a hotel?

The role of a night porter in a hotel is primarily associated with being on duty during the night, which is accurately reflected in the correct choice. Night porters typically handle various responsibilities that arise after regular hours, ensuring the safety and comfort of guests. Their duties can include checking in late arrivals, managing security, responding to guest needs, and possibly assisting with late-night food or beverage service.

In contrast, the other options focus on responsibilities that are not typical for a night porter. Managing morning check-ins pertains more to daytime staff, cleaning the hotel daily is usually the duty of housekeeping teams, and room service is an area usually managed by dedicated food service personnel rather than porters. Thus, the emphasis on the night duty aspect clearly defines the distinct role of the night porter in the hotel's operational structure.
