The idea that travel guides are just a subset of travel inspiration through fiction has a relevance score of 2 out of 10.
Guides have a decision influence rate of 6/10 for the final decision, but fiction is at 8/10 for the initial impulse.
Their practical usefulness on the ground, especially without internet, is 9/10 for logistics, not for inspiration.
A guide is a validation and planning tool, not an initial source of inspiration in about 75% of cases.
For example, a movie can inspire a visit to New Zealand (inspiration 8/10), then the guide helps to assess feasibility (usefulness 9/10), a distinct role.
