Let's let go of the past: the idea that local events are always a determinant component of destination validation seems a bit strong.
Honestly, if we hadn't already invested so much attention in this statement, we would see that it is not universal, but rather a contextual variable.
It's not a systematic step for every trip, but something to consider case by case.
For example, a business trip to Abidjan will not be really disrupted by the Mask Festival in Man, even if both are in Ivory Coast.
