We booked a river cruise back in January of 2020 for a trip that was planned for October of 2020. The trip was paid in full shortly after booking. Viking canceled the trip in August of 2020 due to covid. At the time they offered us the ability to rebook for 2021 and gave us 125% of the value for all our troubles. We quickly rebooked. Who wouldn't?? Now they will not let us go on our cruise this October because we have not been vaccinated. That is not what we agreed to when we gave them over$10, 000 back in January 2020. No vaccine existed back then. They refuse to give us our money back. This is theft, fraud, and deceit on the part of Viking.
