How does the use of the sweeper car affect the total cost of the trip?

The use of a sweeper car can increase the total cost of the trip to the Camino de Santiago, as it is an additional logistical support and transport service. However, it is an investment that provides safety and comfort, especially for groups or pilgrims with limitations. By sharing the costs among several pilgrims, the cost per person can be reduced, making it a practical option on certain stages or more demanding routes.
