I just finished the camino del norte a week ago on bike. I never used any guides, just my gps on my phone to get through it. I tried to stay in an albergue like once or twice, but they were usually full (and quite smelly). I always found pensions super easy and they were usually around $30 euros a night and because of the low season, always had rooms available even when I was showing up around 6-7pm every night. I stayed in the monastery in Mondoñedo and Sobrado, other than that, I found it pretty simple to find a place. In Santiago, within 5 minutes or arriving to the cathedral, I had 3 different people come up to me asking me if I needed a place to stay. The Camino provides. I honestly have no idea how anyone who doesn't speak any Spanish can do this, because I don't think many Spaniards on the camino speak English.
