The fees for the flight + hotel finder, are prorated to total passengers, it shows the average price per passenger.

This is because the system performs some calculations so that it comes out cheaper to book the flight and hotel together than separately, as there are special rates for only this product.

For example, if you book a flight + hotel for 2 adults and 1 child, the system applies the discount of the child, and  adds  it to the price of adults and divided by 3, thus leaving the same price for each passenger, but child with the discount applied.

But really both, children and babies, pay much less than adults, always depending on the supplier and the airline.

The best way to find out the real price for the adults and children consequently will be by doing the same search but only for the adults.
