Here in the States we typically travel in May or Sept because kids are in school and prices tend to drop. We were looking at May, but my wife wonders if weather a bit warmer in Sept. Our basic trip plan is Oslo and the fjords, and still working on how to do the fjords. One book I picked up said things start closing down in Sept and prices go up for rooms.
We like to cook in room when we can. In Spain we rented apartments two years ago. They were similar price to hotels. Seemed to be popular thing in Spain. Is there a similar popular accommodation type in Norway? probably will stay in Oslo and Bergen, though that is still open
Fjords? Any suggestion of best way to see the fjords. We are looking a train from Oslo to Flam boat to Bergen and train back to Oslo. But same guide book says Geirangerfjord is Norway's #1. but maybe that is because of cruise ships. I would like to avoid the big cruise ships.
