I suspect the acogida is for when Rincón de Sandra is unavailable for some reason - no Spanish village is going to let you sleep on the street, but nor are they going to provide free accommodation when there are conventional options. When we stopped in Monteagudo, the Rincón was in fact full so she opened up what we suspect was a family property at the bottom of the village. No complaints, it was actually quite luxurious, but no mention of an acogida. Personally, I feel that the kindness and hospitality we met on the Lana was almost overwhelming at times and I wouldn´t want to take it for granted. As for using Wikiloc on the Lana, it´s not just common sense, it is self preservation.
