My family and I (my spouse and our two sons, ages 13 and 16) will be traveling from Bergen to Oslo on June 15–16, following the traditional Norway in a Nutshell itinerary. I would normally book through Fjord Tours, but since they classify my 16-year-old as an adult—whereas if I book the tickets myself, he qualifies as a child on some legs—I’m considering handling the bookings independently. I believe I have a good understanding of what needs to be booked, but I can't do so yet since tickets aren’t available until 90 days prior.
I know June is a busy time so is there a risk of the trains, the bus from Voss, or the ferry selling out if I wait? Thank you
