Honesttly, Viking the only line I have seen that is testing everyday, Personally it affected my decision to do Seabourn in the Med this summer instead. It is already stressful to test pre and post trip. I would have a hard time enjoying myself is constantly worried. At the premium price they charge, it is not worth the stress compared to the other luxury brands. I will sail them again when this is over, I actually already had Covid and have been vaccinated and boosted and Still scared of being quarantined!
