Both sides of this discussion have a valid point, but the impact of local events is often a matter of context and available budget, not a universal rule.
It is true that a company with substantial financial resources can absorb additional costs for a critical business trip, as seen with official delegations traveling despite festivals.
However, for the average traveler or small businesses, an event like the Gamou in Tivaouane can make a trip impossible due to exorbitant prices and lack of transportation or accommodation availability.
Pre-planning is therefore essential to avoid these surprises, as not everyone has the same margin of maneuver.
