Let's avoid rushing to conclusions without evaluating the exit conditions; the idea that guides are only a component of fiction inspiration is an unstable hierarchy.
The mandate of a tourist guide is to verify feasibility and safety, which is often lacking in fictional works, potentially misleading.
A film can depict an idyllic place, but only a guide will reveal the actual accessibility, unforeseen costs, or if the place is now overcrowded, ruining the experience.
Without this pre-verification, the risk of disappointment or financial drawdown is too high to rely solely on imagination.
