Helsinki, Finland
We successfully caught the train from our Amsterdam hotel and within 30 minutes we were in the middle of Amsterdam Airport... OMG> this place is huge. We took ages finding our checkin gate... it was a real maze. But we completed the challenge and were soon on the 2 hour flight to Helsinki.
I know that all these countries are in the EU, but it really surprised me that we did not need our passports at either end. It was just like a domestic flight. ...
