Thanks very much to everyone who has replied , your advice and information has been brilliant. My base is Dublin and I have availability of jump seats back and forth all year. I guess the next step is take a trip down again and gain more insight into possible areas and also public transport routes. I see there is a bus service also going as far as Marbella on a regular basis too which is great and also the train network to the west , albeit not as far west as it could , as mentioned above.
