Forget the dichotomy between fiction as inspiration and guides as practical tools; it's a false lead.
The real question is how to trigger the desire to travel in a pragmatic and accessible way, regardless of the source.
I think it’s better to have a dream catalyst that integrates both, where a travel guide can also be a source of inspiration just like a film.
For example, a Lonely Planet guide with traveler stories and beautiful photos can ignite the spark for a family trip to Costa Rica, long before a film does.
