The staff was excellent - from the captain to the housekeeping gals & guys. Each and every one was willing to do whatever was needed for the guests. Our cruise director (Vicki Van Tassel) was the best! She made every event memorable. The Viking Sun is elegant - lots of beautiful wood & leather furniture plus floor-ceiling windows in most common areas. The Sun never felt crowded. You could always find a spot to relax with friends or a book. The spa is amazing and never crowded. The lecturers were all very informative and not at all boring! Really liked that the lectures were all available to watch on TV in case we missed them. We both enjoyed the entertainment and we attended all but 3 performances. The food in the dining room and the specialty restaurants was excellent. The pool grill was especially good and even the buffet was well above average. The celebrations for Christmas & New Years were over-the-top and far above our expectations (and any past experience on larger ships). We enjoyed all of the ports as they were new experiences for us. In each port (except 1) we did the included excursions. Only one was below our expectations. This was a segment of the 245 day Ultimate World Cruise.
Cabin was spacious with plenty of storage. Never heard any noise from corridor or adjoining cabins Over-hang above balcony kept sun off (except at sunset), but also made picture taking difficult.
