Tour guide

A tour guide was an individual who provided historical, cultural, and technical information about certain landmarks and installations, usually to visiting tourist groups.

In 1985, Gillian Taylor, assistant director of the Cetacean Institute, acted as a tour guide at the institute. 

In 2377, a tour guide showing a group of children the Pathfinder Project facility at Starfleet Headquarters was present when Reginald Barclay surmised that the Borg had intercepted his data stream to Voyager. 

In 3074, and in an unknown future, tour guides at the Kyrian Museum of Heritage presented vastly different historical accounts of the events surrounding the Great War.
