Hi there - it really is very simple. You walk, then you get somewhere with a sign pointing to an albergue and you decide if you want or need to stop. If you don't, move on - maybe check the guidebook to see how far to the next place - and if you feel that you do, go in and ask for a bed. Sometimes you hear about a particular albergue you don't want to miss and then you go there. Sometimes you just want to find a hotel, lock a door behind you and sleep for 16 hours straight, and then you do that. Sometimes the albergue will be completo - full - and there might be another one in the same village or town, then you go there. On the stretch between Ponferrada to Santiago in July lots of places will be available. No need to worry, try to look forward to the freedom of choice instead, the freedom to follow your gut instinct, listening to your body, stopping when you want or moving on even if everyone else stops. You'll love it!
