1) Norway was simply fabulous, breathtaking natural beauty! Estonia caught us off guard with its history and Tallin is one of the best preserved medieval cities in Europe. The Old Town sections were fascinating. We participated in all the included excursions and found them to be interesting and well organized. We purchased the Peterhoff Palace & Gardens tour for the 2nd day in St. Petersburg and were very impressed with whole excursion. We felt most of the tour guides were top notch and did a great job keeping track of everyone.
2) For us, the Welcome Show with the fantastic singers/dancers gave us a warm friendly feeling. The Norwegian song, "Welcome Home" was very touching. The Captain's and selected crew members welcome was the best we've ever attended. It all seemed to set the stage for a wonderful cruise.
3) We really don't know of any criticisms of the ship. The ship is so beautiful and easy to navigate. We loved the smaller number of passengers onboard, it rarely felt crowded. We tried to enjoy the tapestries with explanations and artwork (Viking Art guide app). We visited all 3 pools, the spa, sauna, steam, snow grotto. We listened to all the talented musicians on board and attended quite a few of the theater shows. We listened to several of the informative speakers, port talks and viewed the speciality movies, like the documentary series about the Vikings.
The stateroom was above our expectations and the bathroom is by far the best we've ever had!
