Who pays the price when we say that travel companions determine the destination?
Often, for the little traveler or someone facing emergencies, the influence of companions is a constraint imposed, not a choice.
The fate of one dictates the route of the other; if a parent needs to go to the hospital abroad, the companion is there out of necessity, not by choice of destination.
The financial cost, which is heavy for the most vulnerable, crushes any discussion about group preferences.
An invoice for a visa or ticket can wipe out any discussion about the influence of companions, like when my sister had to take out a loan for her sick child's company in Dakar.
