In reply to Red Rover:
There is a network of cheap hostels for the pilgrimage, obvioulsy proper pilgrims will get firts dibs, however I would very much doubt they would turn anyone away if they had room. On the whole we found the area great value for money. Food comes in huge portions and sharing a main is very accepatble but seems odd to us brits, which makes eating out cheap. We found accomodation cheap also.
ie A lovely little en suite room in Santalina Del Mar about 39€ for two, no brekkie.
