Does anyone know if your passport (USA) is checked and stamped when traveling between countries like Croatia to Hungary to Austria to Italy to Malta, etc. etc? I am thinking of flying to Zagreb (cheap airfare from the US) and just traveling around Europe. Not exactly sure where I am going yet, but know I would like to go to Budapest, and eventually to Malta via Italy. I don't have a lot of pages in my passport so I don't know if I should get new passport now, or be ok with the 5 pages I have. I know when I went from Spain to Portugal and back no one checked my passport and it didn't get stamped.
