Hi, amigo,
Álvaro Lazaga is walking the camino de Madrid backwards (on his way home to Benidorm from Santiago) and has spent one night in the forest, one night inside a little church, and one or two nights at friends’ houses. Albergues closed in most of the places except Puente Duero, Santervas (or whatever the name of the town is where Ponce de León was born) and Castromonte, I think.
You can see him
here.
I suppose things could get better, but right now it looks like it could be tough. I do think he has passed by several hotel options, so you might be able to patch it together if you’re willing to do that.
