I am trying to plan ahead for next summer to see how much it would cost and how long I would need to travel around the Mediterranean. I have a month (4 weeks) and wanted to get in Spain, France, Italy, Croatia and Greece. I have traveled around Europe before but never to Croatia and Greece. I was wondering if anyone had suggestions or into on how to get from either Rome or Venice to Dubrovnik in Croatia or Greece. I am not sure if I should just be looking for a cheap flight or or trains/boats alone would work. If you have any tips on traveling around these places, let me know! Thanks!
