My husband and I will be going to Helsinki in June (for a work conference) but when it's over, we'd like to take some time to see Norway too. I had planned to spend about 5 days in Norway. I know I want to see the Viking ship museum, some scenic highlights (maybe the Oslo-Bergen train or Norway In A Nutshell tour?), and the Midnight Sun/Arctic circle area. Can anyone suggest which attractions/cities/etc should not be missed. Is 5 days long enough to do all the things I want to do? Any suggestions on itinerary would be greatly appreciated!!
