Reducing the problem to its inputs reveals that the impact of local events on destination planning is not always the decisive factor. The causal mechanism is that the local event only becomes crucial if the traveler attributes a specific intention to it.
If the purpose of the trip is relaxation, a noisy festival becomes a constraint to manage, not a validation element.
For example, holidays on the Belgian coast during an event like the Middelkerke Comic Strip Festival may mean more crowds and higher prices, without adding value if the goal is pure rest.
The event is a sufficient condition only if it is a direct reason for the trip; otherwise, it remains an adjustment variable.
