im from portugal. in my opinion you should travel by train (from a country to another). if you want to move around cities i suggest getting an combined ticket. like underground plus bus plus whatever you need.What is the best way to move around Europe?

depends on where to where, and you have to adjust to that..if destinations are pretty big i am sure u can find some cheap flights.
