Saga has suspended all tours and cruises on Spirit of Discovery until June 1.
The operator is offering to rebook customers due to travel up to the end of June without fees to any alternative holiday between September 2020 and December 2021 through its Peace of Mind policy.
In addition, it is offering £100 per passenger off replacement European holidays, river and ocean cruises, and £200 off long-haul holidays when rebooked.
