I am going to be travelling to Oslo in Feb 2014. I arrive at the TROP airport in the afternoon and I want to know what is the best way to reach the Oslo city centre? I have done a bit of reading and it seems I can either take a bus the entire way or take a shuttle bus and then a train. Both the bus and the train I believe arrive in the same spot in Oslo (bus and train station next to each other?). Both options take the same amount of time to reach Oslo and cost the same.
So basically which option is easiest after a long flight from BC Canada? Is it possible to purchase a bus or train ticket in the airport when I arrive or do I need to book either option ahead of time?
Thanks for the advice :)
