We're going to be staying in La Linea for a wedding, and then moving on to Marbella for a week afterwards. We're flying in to Gibraltar, and out from Malaga. Were thinking of hiring a car to get from La Linea to Marbella, and then to the airport in Malaga, but think it probably is not a good idea to hire from Gibraltar airport. Are there reputable hire car companies actually in La Linea? And is it a good idea in the first place, or is there an alternative?
