Hi, although i have been to Torrevieja many times over the past 20 years i have never caught a bus. Can anyone tell me please how to go about it? Can you pay as you get on or do you have to pay in advance from somewhere as you do in Italy? Also i plan to go from our apartment near the salt line on the sea front into both Alicante and Cartagena for the day, any ideas of bus numbers or where to catch them would be appreciated...Thanks.
