I'm looking at visiting Tromso 26 December - 30 December. I have a second period in mind being 3 January - 7 January. I prefer to visit in the December period but I need to ask about how much of Tromso shuts down between Christmas and New Year? I assume tourist activities are safe but what about shopping centers, restaurants etc? I just want to make sure it won't be a ghost town during our down time in that period. Where I live in Australia, people go crazy in the festive season and so many businesses shut down for sometimes over 2 weeks from Dec 24 until the first Monday of January.
