Is a local event always a disaster to avoid when planning a trip? No.
Cut the noise: the impact of local events is often exaggerated and depends heavily on the size of the destination.
A large city can absorb a major event without ruining the experience for unaffected visitors.
For example, thousands of tourists in Montreal during the Grand Prix never see the circuit, enjoying other city attractions.
The parsimoniousness would tell us not to flee an entire city because of a single event if you do not plan to participate.
