Me and two of my friends are right now studying abroad in Rome and will be spending two extra weeks after classes end traveling around. So far we have planned the first leg of our trip (Rome-Florence-Milan-Oslo-Berlin). We would really like to go down to Croatia for the last 4 days of our trip and take buses or trains down to Dubrovnik, from which we'll take a ferry back to Italy.
Our problem arises from the connection from Berlin to Croatia, mainly because of prices and timing. We have looked at pricing for airfare already (a fairly steep 100 Euro), and it's a little too much for what we'd like. Are there any suggestions on alternative ways to travel from Berlin to Croatia cheaply? Thank you for any help
