Hi, so my friend and I are traveling to the greek islands next week and have just received our 4-day paper-passes. We are trying to fill it out correctly, but we are confused by the line about inbound and outbound travels. As far as I have understood, those are the trips you take to and from your country of residence. But we will only be using our pass in Greece, and therefore wont be traveling in our home country, so are we just supposed to leave the space blank?
