Just a quick note to say that I've been questioned the last couple of days by hospitaleros regarding my lack of stamps, despite having walked from the coast up to Merida (am currently in between Merida and Caceres). Basically there aren't albergues to mention along the Mozarabe route, and I never bothered asking hostales to stamp my credenciale. On a couple of occasions ayuntamientos were open when I passed, and I popped in and got a stamp - but it wasn't a priority for me. The hospitalero today was fairly convinced that I'd taken a bus, particularly because I arrived early. Although we managed to reach a good and amicable understanding, to avoid such pointless discussions, it might be worth getting the hostales/hotels you stay at on the way to stamp and date your credenciale. I am sure it is a one off kind of situation and I simply wasn't bothered about whether I had a credenciale full of stamps or not, but I can imagine it could be awkward if there was a big demand for places or something.
