I'm going on a Mediterranean cruise (ports include Barcelona, Nice, Livorno, Rome, Naples and Sicily, then back to Barcelona). My nationality requires me to get a schengen visa - however I was only given a single entry schengen visa. The ports I will be visiting are countries within the schengen agreement (Spain, France, Italy) - however, we are cruising on international waters. Will I be safe - meaning, will I be allowed to enter Barcelona again?
