We spent the least amount of time in Oslo, per Anne's recommendation, and that was a good move. It's like many other large European cities. We were glad to have more time for the Western Fjord region of Norway.
The kids enjoyed the Viking Village and the Viking Museum the best. But there wasn't anything they didn't like on this trip. The itinerary Anne designed for us had a good mix of things to keep the kids interested. The kids also loved the breakfast buffet at all the hotels!
My husband and I enjoyed the scenery, all of the different modes of transportation which allowed us to focus on the sights as opposed to having to drive.
