Ship. Words that come to mind about the ship: refined, tasteful, understated, quiet, slow-paced. This description could also be about fellow passengers, with the addition of "very friendly" and "good company." At age 77 I'd guess (and it's only that) that I was younger than the median age of fellow cruisers. This is definitely not a cruise for the middle-aged or younger. By way of contrast, the Viking Sea itself is only a couple of years old, and in almost-like-new condition. Our cabin (see separate section) was excellent and Wi-Fi worked fine, as did the TV (though no CNN).
One nice touch the ship has is original art hanging throughout. We used a book in our room to go around an look at all or most of it. (Unfortunately this is not a book you can buy or take with you, we were told.) A lot of the artists are Scandinavians, but not all. There's also an app you can use for your art tour, but I could not get it to work satisfactorily. Only negative was one picture in the back of The Restaurant that was hung upside down, and which I suggested they correct.
For me the dining experience was top drawer. I had only one entree that was just average, though my wife had a couple in that category. We ate in the main dining room, called "The Restaurant," except for one night at the Chef's Table and two nights at Manfredi's Italian restaurant. We also ate some lunches at the Pool Grill, very good, and twice, once for lunch and once for breakfast, at Mamsen's, which I'd say was the weakest dining venue. The World Cafe was great for lunch and breakfast, and offered some theme buffets in the evening (e.g., Caribbean, Indian) that we did not visit. Overall, excellent dining -- the best cruise ship food we've ever had. The service was adequate, though sometimes harried in The Restaurant. I should add that we used room service for breakfast five or six days. The deliveries were on time, and the hot food arrived hot. Excellent service.
Overall the cabin was fine for us, though the bathroom was a little small (in our cruise ship experience) and the bathroom lights at the mirror over the sink weren't great. Oh, and the hot water temperature in the shower wouldn't hold steady. But, still, an excellent room overall. The Penthouse Veranda is not a penthouse, top of the ship, but rather just a middle size room, neither the smallest or largest available.
