In this jurisdiction, the same fact is read differently: the impact of local events on trip planning is not always a decisive factor, but often a secondary consideration that can be ignored if the main goal is economy or simplicity.
But really, do you think everyone has the luxury to choose their vacations based on a music festival or a football match?
Here, in Portugal, most people first look at the price of the plane ticket and the availability of accommodation, especially if they are traveling with family or on a tight budget.
If a local event falls conveniently, so much the better, but it is not the main driver of the decision; for example, if I want to go to the Azores in August, I know prices will be high, event or not, because it is high season.
