(By the way, this photo has nothing to do with the Italian Riviera...just thought it was funny).
So far we've got:
Hotel Aalborg in Amsterdam July 02-05 ($420)
A friendly student that graciously offered us a spot to sleep in Munich at the StudentStad July 06-09 (free, woohoo!)
Locanda Acquavita in Venice July 11-14 ($460)
Cinque Terre Residence in Vernazza ($800)
Now we have to figure out how to get to Greece from Italy (looks like a train to Bari, then a boat over or some sort of over night boat from Rome if that exists). Then we need to find accomodations in Greece (picking an island is very difficult) and some place to crash in Dublin too. I hope couch surfers come to the rescue in these two places because it looks like it'll be tough to find a couch surfh in Venice or Rome.
