Necessary to book in advance?

The question was:

I will be walking the North Route beginning May 23 from Irun. I would like to ask if it is necessary to book my overnight stays in advance at the albergues now that technology seems to be offering that. I really don’t want to feel the pressure to do so as I won’t always know how far I will be walking. Has this become a necessity now, or is it just more of the bed race fear at work?
