We have booked our original cruise with Viking in September of 2020 for the sailing in July 2021. Eastern Europe Passage July 19-31, 2021 #6165887. This sailing was cancelled due to COVID-19. They gave us a voucher for 125% of the price we have paid. Viking have informed us that we could get a refund if we wanted to. My husband and I wanted to travel, so we accepted a voucher and re-booked it right away for a next available sailing - Aug 31-Sept 10, 2021 #6332421. At the time of booking I have asked what was their COVID-19 protocol, and the answer was: testing within 72 hrs and mask wearing on the ship. We agreed to this and booked. In July 2021 we received our flight itinerary and an email with Viking NEW HEALTH PROGRAM, which requires ALL guests to be vaccinated. We have a strong conviction regarding vaccination and are not going to partake it now or in the future. I have called to Viking multiple times with desire to resolve this issue: we are healthy individuals and happy to take a test and wear masks, but it did not go well, we were supposed to give a proof of vaccination. In the end we had to cancel our booking and received our vouchers back. We have been refused to get a money refund. So now we have a problem: we can't go travel with Viking (we really wanted to) and we can't get our money back (somewhat $10, 000 which is a big money for us). So, please, help us to resolve it.
