I'm having difficuly figuring out which bus company serves the route Jerez to Sanlucar de Barrameda. Looks like it was Linesur, then changed during 2014 to Valenzuela, but I can't find a schedule or information. I have found SdB to Cadiz, but not SdB to Jerez. We are looking into travelling to Cadiz from Jerez with a stop in SdB. Is anyone familiar with this?
