What role does a step-on guide typically play in a tour?

The role of a step-on guide is specifically to lead the group during certain segments of the tour, particularly during sightseeing activities at designated locations. This type of guide typically boards the vehicle with the group at a particular site, sharing detailed information about the attractions and answering questions, thereby enhancing the visitors' experience with local insights and expert knowledge.

This approach allows the main tour operator or driver to focus on transportation logistics while ensuring that tourists receive valuable context about what they are seeing during their visits. Step-on guides are often employed in larger cities or specific attractions where in-depth commentary is beneficial. In contrast, the other roles mentioned, such as leading the entire tour, providing transportation, or managing accommodations, fall outside the specific duties of a step-on guide, which is why this choice is the most accurate.
