We would like to take the early morning train on August 18 from Flam to Myrdal to hook up with the Myrdal-Oslo train. It shows that the train is quite heavily booked for the 08:35 departure. I tried to reserve from the site; however, it says it will only book groups of 10 or more. Is there another site where I can book two people, or do I just show up on the day of and hope that there is room on the train? Thanks!
