Tour operator (Gallifrey: A Rough Guide)
From Tardis Wiki, the free Doctor Who reference
One tour operator who was familiar with the Imperial Datanet was among the parties in the post-War universe who organised commercial temporal tourism into Gallifreyan history, now that Gallifrey had been destroyed and passed into history itself. They wrote a tour guide that logically doubled as a history of Gallifrey. (PROSE: Gallifrey: A Rough Guide)
