Having left Adelboden in Switzerland to go to Frankfurt-Hahn airport it became quite obvious that somewhere between Frankfurt and Hahn we were lost. It was the middle of the night and quite worrying. This airport is the biggest kept secret in Germany. Although we found it eventually and in time for our flight I am still not sure exactly where it is in relation to either Frankfurt or Hahn. I think Ryanair need to give passengers more of an inkling to its location mystery tours can be fun but not when you are trying to catch a flight and not in a strange country in the middle of the night.
