We like Viking because when we check out at the end of the cruise we don't have a huge bill to pay for wine, sodas, bottled water, spa, laundry and shore excursions.
The ship is light and bright and cheery. We'll layed out and functional.
All cabins have a balcony and a shower instead of a bathtub... which we prefer.
Cabins are well thought out and functional. Showers instead of bathtub. We found the Penthouse cabin to have a better closet layout than the basic Veranda. There is a fridge in the cabin stocked with 6 sodas and a few snacks that are refilled every day.
