Bobbie,
The others have already said the important bit, walk what is comfortable for the two of you, 10 days is enough to get over those first aches and pains as the body tries to react to the new and unexpected realities of getting up early and walking all day-you know, what many people do every evening, The Santiago Shuffle. You too have it right concerning the smaller villages, Galicia countryside is magnificant, the towns leave much, very much, to be desired, stop before or go beyond them all. One last word, do not even consider staying at the so-called Pilgrims Pavillion Os Chacotes just before Palas de Rei, a huge cattle barn of a dormitory often jam packed. Any port in a storm? I would rather sleep outside in the rain!
