I have a few more questions about booking the individual legs of the Norway in a Nutshell route because I'm going to book each leg of the journey myself instead of doing the package. (trying to save a few dollars) :)
For the trains...I'm going to use the NSB site (or maybe even call, as has been recommended)
For the boat ride from Flam to Gudvangen, I'm going to book through the visitflam website.
I'm not sure exactly how to book the bus from Gudvangen to Voss. I've looked at the nettbus site, but I'm a bit confused by that site. Can I just get bus tickets on the bus? Or should I buy bus tickets ahead of time? We'll be there in early July. I know it will be busy at that time so I want to make sure everything is booked.
