i.m reporting from the depths of arczacq about 120 kms from sjpdd. i have my tent with me and have carried it since le puy_luckily its lighweight;i have not used it yet and dont expect to use/be able to use it in spain
several places have offered camping but the cost is about half the cost of a bed so i dont really see the point
On the Camino Frances the villages having available albergues are never beyond casual walking distance so there is almost no need to burden yourself with a tent's weight. I'd have to put a tent's importance even behind that of a sleeping mat and category both as useless weight you likely will discover you regretted lugging with you.
Please, whenever you begin to spend so much time upon your feet, and living out of a pack,"Less is always best", especially near the end of every long day upon them!
The Camino experience is not like a long hike in some remote wilderness.
