From what I have read on the Camino Forum more people are now booking accommodation ahead either a few days before or all of it before leaving home. I was concerned about the apparent "rush" in the morning trying to get to accommodation and claim a bed before others arrived. So, as I wanted to walk for most of the day and not rush to finish by lunchtime, I got my accommodation booked before I leave in just over 2 weeks time. There is concern from "true pilgrims" that this is not the way to do it. I must admit I do understand their feelings but in the absence of speaking French or Spanish and wanting a "gentle" all day walk as well as old age as stated above I opted for "bed safety"!
I have two guide books, the John Brierley one that is good for accommodation and a Rother Walking Guide that I prefer for guidance on the route, albeit the route is well marked.
