Before convincing oneself that local events are always decisive for planning a trip, one must carefully measure the failure conditions and consequences. The risk is not so much the event itself, but the impact on logistics and budget. If a major event like Binche Carnival makes accommodations unavailable or excessively expensive, it becomes a sticking point for the traveler. One must always anticipate what could prevent reaching the main objective of the trip, whether it is a professional appointment or relaxed holidays. Without a prior assessment of the constraints generated, one exposes oneself to additional costs or cancellations, regardless of the event's relevance.
