My wife and I have so far spent two days in Milan and have hiked the Cinque Terre trail from Monterosso to Riomaggioro (which was quite a feat). We're now headed to Venice. After that we'll be in Vienna for a few days.
After Vienna we don't have certain plans. We'd like to go to Prague and then to Berlin. I'd really like to hit up some Scandinavian cities. We fly out of Paris on the 12.
