3 of us have tickets into Athens on July 15 or so, and out of London in late October. We'll all have a 3 month unlimited Eurail pass, and around 4000 Euro.
The only certainty of what we want to do is Oktoberfest, so we'll need to be in Munich in late September.
Now...we really don't have much of an idea of where to go. Clearly, we're on a budget.
Knock yourself out suggesting
