I am traveling to Sarria at end June to walk the last 100 kms to Santiago with my two teenage sons. For time reasons I will be renting a car in Santander and driving to Sarria and am looking for some advice on parking the rental car for several days in Sarria. Has anyone done this before? Is a B&B more likely to allow this - I would pay them some extra for the privilege? Any advice would be most welcome
