We had sailed on Viking Ocean on earlier occasions (Baltic and Caribbean) and knew that Viking had created a great cruise product with these ocean-going ships. So we chose the Northern Lights cruise so we could check off a huge bucket list item... actually seeing the Northern Lights, and have a wonderful time while doing so.
Our cruise experience was uniformly excellent from embarkation at London and disembarkation at Bergen. The comfort of our cabin, the professionalism and friendliness of the crew, the delicious cuisine, and the talented entertainment. It was all great.
Of course, it certainly helped that even though it was still winter at those high latitudes, our weather was near perfect for the whole cruise. So we had multiple nights on which we could see the aurora.
