I met a number of people who were walking or cycling the VDLP in reverse in October/November. I think they were enjoying it and it must feel good to head toward the warmth of Andalusia as winter sets in.
It's true that you'll meet different people every night at the albergues. But I think you'll find it easy to connect with them. On this uncrowded Camino, I think that most pilgrims are receptive to encounters with new people. You also get to enjoy brief encounters and exchanges of information with pilgrims who are heading north. I think you should have a great time.
