You can get a vacation in a paradise for a quite reasonable price
The human desire to travel is not just a wish to have a good rest somewhere on a sunny beach, but also a semi-conscious striving for knowledge – knowledge of the world around oneself, knowledge of new sensations, broadening one's horizons. For most people, the most acceptable method to indulge in such knowledge is to purchase a tour from a travel agency, especially since posters advertising tour operators' services are hung on almost every lamppost.
At the same time, another desire of the traveler is easily explained – the wish to save on the trip so that upon returning home one does not have to live on bread and water. That is why the phrase "last-minute tour" is so pleasing to the tourist's ear.
"Last-minute" tours differ from regular ones by a single factor – a lower price. In all other respects, the tour package (airline ticket, transfer, insurance, accommodation and meals) is identical to a regular one. A reasonable question arises: why do last-minute tours cost less than regular ones?
Tours start to "burn" in case of force majeure circumstances, when the probability of selling the tour at the standard price is too low. A classic example of such unforeseen circumstances is the illness of a tourist who previously booked a tour, which prevents him from going on this trip. If the time before the start of the tour is minimal (two to three days or a bit more), the travel agency significantly reduces the price in order to manage to sell the tour.
That is why "last-minute" tours, which various advertising posters tell us about, cannot appear earlier than a week or two before the tour, and it is even more difficult to predict the moment of their appearance. Based on this, posters proclaiming "last-minute" tours at any time of the year are nothing more than a marketing ploy, because it is easy to buy posters for advertising, but it is impossible to arrange unforeseen circumstances.
Of course, there are tours whose price is reduced in advance ("dead" tourist season, a drop in demand for tours to a particular country), but such tours do not "burn"; they are simply quite predictable special offers.
