The idea that local events are always a major component of destination validation seems overestimated, to be honest.
Of course, they can enrich the experience, but for many people, the main motivation behind a trip is not a festival or a concert.
Here in Senegal, for example, the decision to travel is often dictated by family obligations or essential appointments, with transportation and accommodation costs being decisive factors.
Cultural events are a bonus when they coincide, not the main trigger.
A middle ground must be found and it must be recognized that their importance is highly contextual and not universal.
