If I were in the author's place, I would say that the distinction between fictional inspiration and the concrete materialization of guides is relevant, because fiction offers an aspiration when the guide provides the roadmap.
However, it is important to admit that this classification lacks nuance.
A tourist guide, like a catalog of destinations, can itself be the primary source of inspiration, long before a film or a book elevates the idea.
For example, flipping through a guide on the wine routes of Burgundy can ignite the desire to travel, independently of any fiction, simply through the discovery of landscapes and opportunities.
