The idea that local events are a decisive factor in validating a destination scores a 3/10 in my decision grid, with the weight of this influence often being secondary.
On a scale of 0 to 100, budget availability and time constraints weigh in at 80, while the appeal of an event is around 20.
My experience with a fixed income shows that cost is a decision multiplier of 2.5 compared to the appeal of an event.
For example, a trip to Paris during the Olympic Games can increase accommodation costs by 300%, making the event a factor of exclusion rather than a validation element.
