Holy Week 2018

I am considering the Aragonés starting March 24, first night in Jaca. Given recent reports of low usage and closed albergues, I am looking for feedback of the likely hood that that accommodations along this route will be open at that time. Is there a tourist office in Jaca or elswhere I might contact for this information? Is later in the year a better bet? It will be my first time on this route and I will be grateful for any suggestions or information. I have a high preference for albergues rather than more commercial establishments, although I realize the need for flexibility.
Thanks.
