I would appreciate any instructions how to get from the cruise ship to the TGM Station in La Goulette in order to make our way into the centre of Tunis i.e. time involved and cost of train fare. I understand it is better to pay in the local currency or do they take the euro or dollar? I know its only a short distance and takes only a little time to arrive there. I have only been to La Goulette once and know the main street there. Thanks in advance.
