Considering local events is indeed an integral part of planning, but its importance varies greatly depending on the type of trip and the traveler's goal; it is not always the decisive factor.
It is true that local events can significantly influence the travel experience, sometimes increasing costs or crowds, which is a valid concern.
However, it is crucial to find a just right balance and not overestimate the universal impact of these events, because for many trips, such as an urgent business trip or a family visit, logistics and cost largely outweigh festivities.
For example, a businessman going to a forum in Abidjan will prioritize flight availability and affordable hotels over a local music festival.
