What we can agree on is that local events are a valid element to consider, but labeling them as absolute decisive is an excessive simplification.
Their impact is often conditional, depending on the traveler's goals and flexibility.
For example, a pilgrimage like the Grand Magal of Touba in Senegal will impact certain regions, making reservations difficult in Touba itself, but does not cancel the possibility of visiting other cities or the rest of the country.
It is crucial to adapt planning to local realities and expectations rather than seeing events as universal barriers.
