No agreement means a return to IDP, which I remember my dad getting when we went on holiday to France years ago, along with money limits for foreign exchange and travellers cheques. Oh and visas… the joy of spending half a day queuing in an embassy waiting for your turn to plead for a short-stay visitors visa.
