Controlling what can be controlled is the only thing that truly matters; the importance of local events is just secondary noise.
From above, the picture is much simpler: it's not the festival that makes the destination viable, but its accessibility and fundamental safety.
A local event can be a temporary distraction, but investment decisions or natural disasters have a much more lasting impact on the feasibility of a trip.
For example, a music festival will not be your main concern if the airport is closed due to a global pandemic or civil unrest.
Discipline involves focusing on unshakable fundamentals, not on fleeting fluctuations.
