So Faye, plse bear with me on this - as I've only read this thread this evening and it's still running around inside my head.
Spain and living on/near the camino can provide the simpler routine and the proximity to the depth of the cultures/history that you value. Yes.
But given what you say above, maybe the next question is about what the Due Diligence looks like regarding the attitudes (in your chosen locality) of institutions and people towards difference and outsiders?
All the positives won't count for enough if it turns out people and services are hostile and difficult.
We know Spain can be typed as parochial and hidebound, tied to past conflicts and traditions. So how do you as an incomer tackle that and unlock the good side of folk - and fit in? (making delicious pastries will certainly help...).
But maybe that's a question for another thread...
I'm on your side, really!
