@ LT Fit:
You can see from his/hers Avatar, that the plan is to walk the Via de la Plata.
The question is in the correct thread, but some of the answers are not.
@ Thiagosantiago:
The Via de la Plata is a rather popular winter camino. Besides that there are not that big differences in pilgrims numbers as you have on the CF comparing december/january to july/august. So on the Via de la Plata most albergues are available the whole year, whereas on the CF they have lots of additional accomodation in summer. Only difference on the VdP is that the hospitaleros are not waiting there for you. You have to phone and/or to collect the keys.
Best you check availability with Gronze and Eroski. If one of them says that the albergue is closed, check alternatives. Or try to get some additional Information from the local association when you start in Seville.
