C&I when leaving Europe on a TATL voyage?
At which port is customs and immigration done when leaving Europe on a TATL voyage bound for North America? Say if the cruise ship leaves from Italy and stops in Spain, France and/or Portugal along the way (all countries in the Schengen zone), is customs (for duty/tax refunds) at the last port in the E.U. or port of embarkation? Similarly, what about passport control? My wife will be entering the E.U. with a passport where she wont be stamped going in (or out) but will present a different passport to the cruise line to make it easier for the drones uuuhh staff on board.
Not as easy/clear as air travel where customs stamping for duty/tax refunds is at the last E.U. airport.
