Yes, exactly. You need to look at flights, often they take up a large part of the budget. In my case, in Lyon, a flight in peak season to Crete, even for a week, can go over 500 euros per person, it's ridiculous.

My probability that the influence of companions is a stable category in the destination selection process is about 40%. I would update it downward if the trip is a professional constraint or a necessity, where the impact of others' preferences is minimal. For example, if my employer sends me to a conference in Utrecht, my colleagues' preferences have less than 10% influence on the destination choice. The role of companions is often conditional, not a universal constant. We cannot say it is a fundamental category without considering the purpose of the trip.
