we will be traveling in Spain for the first time this October. Our group consists of 3 people.
We need to get from Barcelona to Cordoba on October 1st. I've read many good reviews about fast train services in Spain and was ready to purchase our Barcelona-Cordoba AVE ticket (with a short transfer in Madrid) on the official RENFE website. However, I cannot :( RENFE does not like my credit cards (tried different ones multiple times). I have also checked alternative agency selling RENFE tickets (Petrabax), but they do not sell tickets with a transfer (at least not for the trip Barcelona-Cordoba).
We must travel on a specific date (October 1st). Do I absolutely have to buy train tickets much in advance or can I just go to the train station in Barcelona 2 days before the trip and get them there?
If I must buy them ASAP, what other options besides the official website of RENFE do I have?
Any advice related to purchasing train tickets in Spain will be highly appreciated!
