It's a race to the advantage, and relying solely on fiction inspiration to choose a destination is to be lapped by reality.
The idea that travel guides are just a component of travel inspiration via fiction does not grasp their role as leaders on the ground.
Fiction can spark a spark, but it is the guide who provides the detailed game plan, budgets, and realistic itineraries.
For my family, it is the guide who allowed us to realize our trip to Gaspésie, by listing affordable accommodations and free activities, not a novel.
