Having found myself working in Norway I would add a few comments.
The advice about changeable weather should be heeded, the changeability is like the Channel Islands on speed but 15-20c colder.
All the people I have met in Norway have been very helpful and in an aviation context very professional.
The one thing that lets Norway down from a visitor point of view is the cost, just to give you some idea, Small Beer £7, Caesar Salad (small) £16, Bottle of red wine ( house ) £42, packet of M&M's (large) £3.78 all these numbers were pulled from the menu of a moderately priced crew hotel.
If you have money to burn I am sure that Norway is a great place to visit as long as you don't have to meet any time constraints that the lack of VFR weather might force on you. If like me you do have some of the above constraints then I would think it best to point the aircraft south until the Norwegian economy falls more into line with the rest of Europe in terms of retail prices.
