This time I visited Nordic countries and took three cruise ships from all the Nordic cruise companies. The last one was the Siriya mini-tune, which was the best time to compare the three. The last one is Viking, the double cabin area is super small, let alone TV, hair dryer. Tax-free shops are small and have no fun. But the meal was good, the beer was excellent, and the drinks were unlimited. The double cabin of DFDS is very good. There are big bedrooms with TV and hair dryers. It's comfortable and comfortable. The meal is OK, the drink can only have one cup. Tax-free shops are said to be the cheapest, but they are of average size. The top floor is windy and there is no windshield. The interior cabin of Shilia is four people, although it is also upper and lower berths, but it doesn't matter if two people live in it. No TV, no hair dryer. The duty-free shop is very large. On the 6th floor, it sells interesting things. On the 7th floor, there are many small restaurants and shops, which is the best of the three cruises. Dinner is OK. Beer is great. Drinks are unlimited. The top deck has high windshield and is humanized. There is also a window-facing sofa in the floor, which is very suitable for viewing the scenery and can not be comfortable.
