I need an answer ASAP because I only have a 2 hour cancellation window. When I booked on Renfe 2x after canceling Granada to Seville San Justa (one way). I kept getting an error after they processed my tickets that "the IDA" reservation system was overloaded, and that I had the choice to void and start over "later. " So, I have valid tickets for my wife and I for an early train. Does this mean, I can't board at all. I can see if it's the AVE high speed train on a Madrid or Barcelona route. But, am I ok here ? It seems that an early April train on this route would not be problematic. But, who knows ?
Also, the date of travel is listed as "03/04/17" (European format?). I hope I'm traveling on April 3rd.
