Can one use the 6-day Greek island pass, which includes the possibility of a return trip from Italy to Greece (Ancona-Patras-Ancona), ‘in reverse’?
In other words, imagine one is already on a Greek island and uses the first travel day to reach Piraeus, the second travel day for Patras-Ancona, the third travel day for Ancona-Patras, and the remaining days for travel within Greece. Is this allowed?
Many thanks!
