The capital is limited, and reducing destination validation to the impact of local events ignores the budgetary and time realities that dictate most travel choices.
Time is short, and local events are a luxury, not a decision pivot for most households, especially when juggling school holidays or federal holidays.
In Quebec, for example, we often have to ration our budget and days off, making financial constraints and availability much more decisive than a major festival.
The idea that local events are a decisive factor diminishes in importance compared to the necessity to leave when possible, not when desired, otherwise flight and accommodation costs become unbearable.
