If you do drive then be aware it takes around 13 hours from north to south with a couple of stops etc.. About half way down is some serious wine making country (Nuis St George) and some very picturesque B&B's if you want to break the trip. As mentioned earlier be aware of the speed limit as it is not only expensive but CASH only. Worth carrying around 150 euro's as otherwise you will have your car impouded whilst you trek to a cashpoint! When you get south there are some great places all along the coast but if you get a chance then drive into Italy for a couple of nights, marvellous!
