We have only done one of each. Both gorgeous ships.
Seabourn cabins better.
both have laundries.
drinks included on Seabourn, Viking need to upgrade to be fully included.
Viking has walking deck, Seabourn doesn’t.
Viking included spa area superior to Seabourn.
Food subjective - both very good, I would say Seabourn though slightly better, room service amazing and caviar on demand
viking doesn’t include tips
service - we had major problems on both cruises but Seabourn were just terrible - I was shocked how poor it was.
Viking includes basic shore excursions - we didn’t like this as too basic.
Viking felt more casual but fellow passengers less friendly. Seabourn tends to attract a fun mature crowd, Viking passengers felt conservative.
Dont believe the Seabourn is luxury and Viking is Azamara level hype - not true.
There was very little entertainment on Viking and zero nightlife on our cruise. Also Seabourn do some great “events”.
We have only done one of each. We were so disappointed in Seabourn service. Viking didn’t suit us as we don’t want included shore excursions and like a little more fun.
