When we moved to Belgium in 1970, we flew to Brussels but separately, as DH had to go before me and I followed a few months later with a very active three year old in tow! Our bank account had been transferred so I don’t remember currency restrictions being an issue. When we came home, with two children in tow, we drove, in a very small car, to Ostend and crossed to Dover, then drove from Dover through the night to to South Wales without having been able to have the headlights changed over so they weren’t lighting up very much of the road! Trying!
