Here's the story: saying that a two-week stay forces you to go in low season to manage the budget, forgets a key character: the student.
We don't always have the luxury of choosing our dates; my exams or an obligatory internship often dictate my only travel windows.
So, even if prices are higher, sometimes it's the only window of opportunity.
For example, for my spring vacation, it was either go during the peak season at an exorbitant price, or not go at all, even for a short duration.
