I'm going to be going to Sandefjord for two weeks to visit my son and his girlfriend. This will probably be a once in a lifetime trip for me, so I would love some tips on planning it so I make the most of my time. First - what time of year would you suggest? I'm debating between a Feb. trip or a May trip (I'm from Northern MN so cooler weather doesn't bother me). I'm big into photography and wonder which time of year would be the most beautiful? Second, what are the "must see" things I should consider going to in Norway? And finally, I'm thinking of planning a 2-3 day excursion on my own during the week while my son and his girlfriend are at work. I love water and I love mountains. I was thinking about going to Flam and/or Bergen. Any other places I should take a look at instead? Any ideas are welcome - I have plenty of time to plan!
