Burning tour is a ticket for which the tour operator significantly reduces the price, usually 1-3 days before departure. The money of the tour operator paid for plane tickets, transfers and hotel rooms will literally burn out if those who want to relax are not found in the shortest possible time. Therefore, companies deliberately make losses to cover at least some part of the costs: half is always more than nothing.
This means that the tour will be selected taking into account the wishes of the customer. Such vouchers are ordered by those who want to visit places far from the mass pilgrimage of tourists, as well as just people who appreciate rest.
