Honestly, does the actual cash flow of your holidays change just because a film inspired you?
Strip the hype: travel guides are not just an appendix of fiction, they are often the practical basis that makes a trip possible.
Fiction can certainly give an idea, but it is the guide that provides the concrete information on costs, transportation, or accommodations.
How many people buy a guide to Paris because they saw Amélie Poulain, without ever having thought of going there before?
It is the toolbox that turns inspiration into a feasible plan, not just a glossy addition.
