Hi ehaldenb, your walking rythm, physical shape, motivation, and more, come into play here. The "El pais/Aguilar" guidebook has divided the CF into 30 days, so I don't know, sounds like u may be squeezing the whole experience, here. Well, acc to them anyway. U may want to start from Pamplona, perhaps, or Puente La Reina...I guess u r refering to bed availability in albergues...I hear there r a lot of pilgrims on the CF right now, don't know of anyone yet whose had to walk further bec of albergues being full. Then again the CF may get crowder this summer, usually does. I'd just take a sleeping bag. During what season would u be walking? Best, xm 8)
