Norway in a Nutshell to Bergen, Norway

This is a kind of spur of the moment trip that I decided to take before it gets too cold and I lose the season. I bought the outbound ticket with 3 days advance and have not booked any hotels or travel or return flight. I looked at the map and kind of plotted out a route, maximizing my weekends in countries where I want to check out the nightlife. Planning to visit about 10 countries that I have nor been to before to get an idea of both the day, night life (very different) and history.
