We volunteer for HosVol which serves a number of the donativo albergues on the Camino. They do require that you take their approved hospitalero course and that you must have stayed in at least three albergues that are either municipal, paroquial, or association managed. If you want to PM me I can give you more information and contacts. I do know that in April our volunteer coordinator for HosVol was still looking for hospitaleros for the year. HosVol volunteers serve a lot of albergues on several different Camino routes. This year we are volunteering for a different organization FICS and
@Rebekah Scott was the one we contacted.
