We travelled to Spain earlier this month, taking the train Seville to Granada; Granada via Madrid to Barcelona. We booked our train travel with Rail Europe. I did look at the Renfe website for timetables however found Rail Europe easier to navigate when booking. After researching, most information recommended forgetting senior discount card and recommended pre-booking. If you need to be in destinations on specific days, personally I am more comfortable booking in advance.
We did have an issue in Seville as our train was not on the departure board. Turned out the train was delayed. We went to the Renfe Customer Service office. They were very helpful reissuing our tickets for another train.
As for choosing level of ticket. We tried both 1st class and second class. For the 20 euro extra, and if it’s affordable for you, it is well worth opting for 1st, especially if it is a longer journey. Second class is fine but more chaotic and the seats narrower, less legroom and not as comfortable as 1st. There are no other perks with 1st, and we had to pay for coffee and snacks. The train between Seville and Granada had no food service. Therefore, I would recommend purchasing a sandwich, coffee/water before boarding. There are cafes at each of the stations in these locations. Trains were clean and the Renfe staff were lovely. Stations were easy to navigate. If you are not sure that you are in the correct area… just ask at the info desk or staff member. Very helpful and we found everyone could speak a little English. Allow time for security as your bags will be put through X-ray. However it is a simple and fast. Enjoy!
