JenWoodside,
If you have a reservation for your first night you might contact that host by email and ask about local taxi service transfering your luggage.
November 1, All Saints' Day, is a holiday observed in both France (Toussaint) and Spain (Día de todos los Santos). Special masses are held. Many families travel during this time to pay homage to their dead relatives. Hence roads and transport may be extra busy. Most businesses and services, but not all, will be closed on this day; generally a few restaurants and bars stay open . Banks and postal services will be closed.
Thus many people will be traveling at this time and hotels will be busy.
Happy planning and Buen camino.
