I booked this cruise in December 2022 when they had a $1999 including air deal. On our Rhine cruise last year we did Air+, a deviation and optional excursion which all add $$. This time i wanted to see how inexpensively we could do a Viking cruise. My wife wanted to go a couple of weeks later so list price was $2,199 each for the cruise. Off that returning guests each get $200 credit and we paid via ACH for extra 3% off. Minimum spend for trip (fare, required tips and airport parking) was $4,250. Optional expenses (airline upgrade to Prem Econ, extra drinks, extra tips, travel insurance, gifts for grands) added $856 for a total of $5,106. I think that was a great value.
