The weighting of travel guides in choosing a destination is underestimated here; I give it a 6/10 impact score, whereas pure fiction inspiration is only 3/10. Fiction is an initial trigger with an inspiration value of 8/10, but its contribution to planning is low, around 20%. Guides, on the other hand, have a value of information of 9/10 and turn desire into a concrete plan with an effectiveness of 70%, validating or invalidating attractions. For example, a novel can make Provence attractive (inspiration 10/10), but it is the guide that allows selecting specific villages and planning optimal itineraries, moving from an idea to a bookable project with a conversion increase from 20% to 70%.
