Went on the Danube River cruise in Sept 2023.
SO many disappointments with this trip I'm not sure where to begin. Although the boat is beautiful and clean, the staff was repeatedly annoyed anytime we asked for anything. The whole week is VERY scheduled and they are constantly telling you to "don't be late" on everything. Me & my husband felt like we were back at work for the week we were on the boat. Meal times are strict and if you miss it, there is NO FOOD until next meal time. If you ask for something, you will be told you need to wait. We were rushed through dinner every single evening and afternoon for lunches. The staff is fake nice and rushes you through each meal. We paid $1200 for a walk-out balcony but only we're able to use it a total of 1.5 days on a 7-day trip. Viking has other boats constantly blocking your view at EVERY port. We rarely sailed and when we did it was at night so again no views.
We paid for an upgraded bar package but each every evening we asked for wine list and either server took forever bringing to us or we never got one. All in all we would never do a river cruise with Viking again. We spent $10k and it was not a great vacay. We also got Covid on last day coming home.
