We booked a River Cruise on the Danube for July 2019 that was cancelled due to covid. We were offered to rebook for July 2020, which we did. We were told we could cancel up to 24 hours of departure. Now, Viking has cancelled the cruise again. We do not want to rebook, but Viking has said we can't get a refund, we can only rebook. We think this is not being handled fairly since we are not able to travel now, and this is the feeling of scored of other people.
