@sunflower,
I walked VDLP from Sevilla to Galisteo, starting April 1st. This was before and during Easter. The albergues were almost full, if not full at night, and on Easter long weekend numbers jumped up creating a problem in Galisteo, many having to taxi 40km to the next available bed.
So yes, you will most likely walk alone, and have nowhere and noone to share a cafe con leche with, but will meet up with the same cohort in the afternoon.
In terms of finding the “fun” or “social” aspect of the Camino, there’s the Frances, then the Portuguese, followed by the Norte and Primitivo equally and lastly VDLP. VDLP last because it has the least opportunities to catch up,with others duing the day in bars for a cafe con leche or tortilla. It’s a Camino for walkers.
But of course you may find someone you click with and walk well with, so that gives you company during the day, you will just start walking together and keep walking, not bumping into people at various watering holes.
Lovely afternoons with good food in many interesting cities, towns and villages.
If you don’t mind the heat, and welcome peace and quiet, I highly rcommend it.
