Considering all the points below, we will stay away from Viking and use other means to see Europe. For the prices they charge for their cruises, you can travel in first class on Canard's or other luxury cruise lines for the same or lower costs.
The cost of our 15 day river cruise was just under $17k. This is equal or more per day to the top tier luxury cruise lines. You can use other options to see major Cities and still enjoy the river cruise experience.
Basically there are no security procedures on the Viking boats. Anyone can board and walk thru the boats.
In our stateroom, our door was opened during the night by unknown person(s). When we woke up the next morning the stateroom door was open. When we brought this to the attention of the Front Desk the staff advised us that it was our fault. After asking for the Captain, we were greeted by the Hotel Manager, Gerald Hauswirth. Gerald accompanied us to our stateroom to check the door lock system. After several attempts that confirmed the defect, he apologized for the behavior of his staff. He was able to reset the door lock. The key to remember there are no means of locking your stateroom door if someone has a key card or the lock system fails.
We selected the AA Veranda Suite ( 324 ). The room was very nice for a river boat. However in the hallway the Viking boat has electrical panels in-between the Suites on the starboard side. During the day and night, we would hear a loud buzzer sound in the stateroom. Three or four times each night we work up to the buzzing noise. The response from the Viking staff was "that is one of the issues on the long boats!
On the Viking, there are no seat assignments. Thus the quality of the service was a function of the waiter. It went from excellent to very poor. The concept of enjoying your meal and talking to your fellow guests . The waiters are focused on serving you the food as fast as possible. The require you give them the full order ( appetizers, entre, desert). There are no substitutions. Thus, you are pressured to finish the meal and leave.
Unfortunately, the lounge is the only place to sit down and talk to fellow guest. The upper deck is closed for most of the trip. This is caused by the 80 locks you go thru.
Drink Package offer:
Viking has a "Drink Package" that you can buy before your trip or on board. We did this only to
to realize the service staff avoids asking you for drinks. My recommendation is not to buy it
There are 2 to 3 waiters that are assigned to the Lounge. Most of the time, they are behind the Bar talking to each other. So to get drinks you have to go to the bar and order. Bottom line their service level is "Poor"
At each port ( one per day), they have free excursions. Most involve "walking tours" with contract tour guides. If you like seeing every Castle, Church and Statue, then this is a great feature. We decided to go to the City Center and do it ourselves.
