Not sure if this advice will help any at this point, but it may be worth reconsidering the character's unmotivated status. If the character is unmotivated then it's going to be hard to get them to Greece because, quite frankly, they have no motivation to go there. You could have an external force like parents or friends get the character there, but it may decrease likability for the character because they aren't making any decision to drive the plot forward. Maybe finding a different motivation that the character does have could be a way of connecting the character to Greece. Like a chess tournament that takes them there, or another passion. Just some thoughts.
