I have checked daily for over two months to book train tickets for our itinerary and have been mostly successful in booking them. I used loco2.com for all of them except one, which only showed up on Renfe, so I used Renfe for that one.
Now I am down to the last two legs: Granada to Ronda on June 3 and Ronda to Sevilla on June 4. I have tried all the websites mentioned by The Man in Seat 61, with no result. The Renfe site says they are not available for sale. Should I continue to check daily, or is the bus a good option between these places? My preference is train if available.
