We are planning a trip to Scandinavia this summer. I would like to see a Norwegian fjord, and visit Copenhagen and Stockholm. We have about 10 days all together--possible? We can fly into one city and out another, which should save some time. 10 year old and 6 year old. We have a fairly generous budget, so would be willing to spend money where it is worth it. Any other bits of advice or recommendations? Thank you!
