How do I reserve seats/tickets for the Norway in a Nutshell tour?
Just go to the website norwaynutshell.com and you can buy everything there. We used it last year - it was great!
We did this about 5 years ago (it was wonderful) I had to book it myself by phone. I found the number on a web page for train travel in Norway. One thing to keep in mind I am not sure if it has changed since I went 5 years ago... but the train station we left from opens after the departure time.. luckily we went the day before to pick up the tickets. If not we would of missed it.
I think you can do it from some hotels.. however because of the time of year we were leaving I had to do it myself.
Robin, my wife and I did this trip last year. You can only make reservations in Norway, so we made them as soon as we arrived in Oslo. We took the day trip to Bergen (day 1), spent a day and night in Bergen (day 2), and trained back to Oslo (day 3) on the night train, giving us 2 full days in Bergen. The train departs Bergen around 11 pm so we had a full two days to tour. The rails and sleeper car were very quiet - I slept like a rock all the way to Oslo!
