I advise that, if you want to do the Flam railway trip, book it yourself. We did it through Saga and were crammed into carriages like sardines, and this was when Covid was still an issue. Our guide shouted at those who tried to board an empty carriage. She lied to everyone, saying that it didn't matter which side of the train we sat because it turns round at the top. It doesn't! We were NOT allowed off the train at Myrdal, despite the excursion details saying we would be. People we sat near at dinner that eveing had enjoyed a leisurely trip by going it alone.
