It is true that budgetary and family constraints are often decisive in choosing a destination, but ignoring the impact of local events would be a mistake.
The right balance would be to recognize that, although events can strongly influence the experience, they are not always the decisive factor for everyone.
For example, here in Senegal, the celebration of Tabaski can make transportation and accommodations much more expensive, which impacts the trip even if one does not actively participate; it is an essential preparation.
