We are two months into a year trip around Europe, currently in the Algarve. The plan is to head East along the Southern Spanish coast, through to France and then on to don't know where. We have two 6 litre British gas bottles and have been advised that we need to have them converted so that we can have them refilled in any European country. I don't understand the technicalities whatsoever. We have found somewhere in Lisbon that will convert them over but didn't want to head backwards unless we have to. Does anyone know anywhere along the south coast of Spain that can do this?
