What is really at stake here is the source of the initial spark, the very idea of travel.
One can imagine a character who, after devouring stories of Marco Polo, feels compelled to explore.
But imagine another character, the travel guide in hand, who suddenly discovers a vibrant illustration of a colorful market in Marrakech and says: "That's where I must go!"
This proves that travel guides are not just compasses, but also beacons.
