We went on the Viking Waterways of the Czars cruise aboard the Surkov. The cabin was roomy enough that we did not feel cramped. The bed was comfortable, and the air conditioning worked well. The food from beginning to end was very good and plentiful. The staff satisfied our needs and answered any questions that we had about the cruise.
Although some reviews have expressed the idea that the traffic in St. Petersburg and Moscow was very crowded and time consuming, we found that this is not always the case, and it did give the opportunity to see more of the city or countryside. In addition, we enjoyed the cruising that stopped off at different ports along the way. The scenery along the way was well worth the water travel.
Many tours are part of the package, but there are optional tours which are worth their while. We were able to get all of our optional tours, but be aware that a few tours have a limited amount of participants that can attend. Just make sure to get your wish list in early instead of waiting around until it is too late. The places we visited in St. Petersburg and Moscow, as well as other stops, were memorable.
We would recommend this trip to other travelers, and we heard from those on board our ship that they really like the Viking China trip too.
