GO THERE, it is an amazing place. If you can, try and coincide your trip when the Northern Lights are going. I was up north when they were blooming and it is bucket list worthy.
It's also a great time as there are amazing deals on flights, depending on where you're coming from. I took my son on a trip when I was done, through Scandinavia and the UK. I got him a flight home with like 5 days advance....Copenhagen to Los Angeles, non stop, $265.00 US.
GO!!!
