Oceania has the most comprehensive itinerary for the Baltic, so be prepared to be tired. Every day but one, you are in port. But that was why we chose the cruise. Who would think we would visit places like Estonia, Latvia and Lithuania that so recently could reclaim their independence from Russia.
Oceania's Nautica is such a comfortable ship . We had sailed on sister ship, Insignia and because they are identical, we immediately felt at home. Our stateroom was fine, clean, good bed, all the necessary items. It wasn't large but we were rarely in it except to sleep. There are so many lovely lounges and places to read, talk, etc. Food was excellent, Loved the wonderful fresh fruit, exciting appetizers and desserts. They get kudos for the terrific ice cream too.
Being early to bedders, we can't comment on evening entertainment. However, listening to others, the shows were well received.
We only booked 2 shore excursions through the ship. Unfortunately, their tours are expensive and groups too large. Found we got better value from using SPB tours and ToursbyLocals.
Also, charges for Internet service are outrageous. There is no reason to charge so much.
But we hope to cruise with Oceania again. Service is terrific; staff friendly and willing to go out of their way to help. Well organized too, embarkation and disembarkation went very smoothly.
