@Anniesantiago, I can't help you with that one but I can't see where a problem might arise for a pilgrim walking to or fro. A pilgrim is a pilgrim and we have all got to get home someday.
That said, a few years ago now I presented myself at the Municipal in Burgos en-route to Moratinos and a Ditch-Pigging session. While just chatting to the volunteer on the desk I mentioned that I was "en-route to Moratinos" to be told that beds were for Pilgrims en-route to Santiago! We chatted some more and I got a bed.
Albergues, unless I've really lost the plot, exist to offer shelter to pilgrims. A Pilgrim is entitled to ask for a bed. It's in the hospitalero/as' gift to grant it.
