Camino Options, pros and cons.
A. Norte (litoral)-Ruta de Besaya-Camino Lebaniego Castellano-Vadiniense. Laredo-León with a few detours.
Pros: Coastal before mountain so beautiful and the one I want to do most.
Cons: At minimum three very expensive nights, variable weather (could be 30C, could be raining and even snow.) Very rural, a few touristy places (Suances, Potes, Fuente De)
B. Manchego-Levante (con desavíos). Ciudad Real-Zamora via Toledo, Ávila, Arévalo etc.
Pros: Lots of cool cities I want to revisit and new places, much cheaper, probable great hiking weather.
Cons: The cool capitales are also touristy, other than the days preceding Ávila, it's pretty flat, a few longish stages, would also have to skip some stages.
