Can the Tarjeta Dorada be used for the Trenhotel between Barcelona and Granada?
I don;t think so because the Trenhotel is a private train. But I am willing to be corrected.
Again no - only on these train types/journeys - http://www.renfe.com/EN/viajeros/tarifas/tarjeta_dorada.html You did not ask, and as much as I like train travel, have you considered flights?
Yes, I have, but I wanted to make a cost comparison. We will fly. Thank you both for replying.
