Getting to Oslo from Europe and North America is easy. There are direct flights from most major European cities and direct (and relatively inexpensive) flights from a number of US airports (NY, Boston, LA, SF, Florida). Connection to rest of the world is available through Copenhagen. The airport express train takes you from the airport to downtown Oslo in less than 30 minutes. Oslo Central Station and The National Theatre train stops are both in convenient distance from the conference venue and the hotels.
