Looks absolutely great - having travelled nearby in the summer (Abisko, Kungsleden etc) I'm very jealous of your winter trip.
We flew with Norwegian, and I was very happy with them except for one small problem. Our overstuffed Vulcans weighed about 23kg each. We thought that our 2 x 20kg allowance would easily cover this, but the automated scales said no. Easily remedied as we took the side pockets off and zipped them together as secondary luggage. One set of pockets disappeared for a while at Oslo airport but it was all sorted in the end and a great trip.
Happy anniversary to you both!
