Me and my family (4 memebers altogether) are going off on a brief holiday to norway on boxing day. We are planning to visit just Oslo and Bergen for the winter season. So i was wondering if any of the peeps here have advice as to what to look out for, interesting stuff etc? Also, what is the best way to get from Oslo to Bergen? I heard train is the most convenient and safest, but prices do approach 400 pounds level with 4 adults. Cheers!
