Let's first reconstruct the argument: it is quite true that tourist guides are valuable tools, especially where internet access is lacking, providing concrete information for planning.
However, it is difficult to consider them as a simple sub-part of travel inspiration through fiction because they operate on different levels.
Fiction ignites a spark, creating a desire to feel an distant ambiance, a longing for exploration.
Guides, on the other hand, are a roadmap to realize this desire, offering practical details to make the trip.
It's like the desire to eat a tagine after a Moroccan film versus the exact recipe to prepare it: one is the impulse, the other the method.
