Talking about a drastic impact of local events is shifting the problem for many families or professionals.
For a business trip to Madrid, the goal is the conference, not the music festival, which then becomes an externality to manage, not an opportunity.

The purpose of the trip should always take precedence, turning the local event into a simple obstacle rather than a decisive factor.
