Plane tickets flying in and out of Oslo 7/10 & 8/6 are already booked. Looking for suggestions in particular on (1) better ways of traveling between locations (e.g. night boat instead of flight or train with EU Rail pass), (2) should I eliminate Berlin because it is too out of the way (3) the fjord nutshell tour - particularly how to visit both Balestrand and the Naeroyfjord and (4) lodging suggestions.
