Hi, Ingrid,
I can understand why you would want to have some company. In case you don't get any responses from the forum, though (after all, we are a miniscule percentage of the people who walk the Camino), you might try what I suggested for
@camino07. If my memory is working, she left Leon alone and went to the La Robla albergue, where she met some people. She had planned to take a bus to Oviedo from La Robla if it turned out she was going to be alone (to continue on the Primitivo, where there is NO shortage of people). As it turns out there were people in the albergue in La Robla so she stuck with it.
I think that during the days you mention, there are likely to be others walking even though none of them get in touch with you. Maybe camino07 can confirm this, and she walked, I believe, in a much less popular time of year. Buen camino, Laurie
