The integration of local events into travel planning is not an unification in itself, but rather a conditionality that can either amplify the experience or make it unbearable. To achieve optimal performance, a fine analysis is needed, not just a simple merging of information. A music festival, like the Carthage Musical Days, can offer a full expression of local culture for some, but for others, it means exorbitant prices and crowds that cancel out any hope of maximum relaxation. The asymmetry of impact must be evaluated to choose whether to aim for a peak benefit or avoid a trough of discomfort.
