My husband and I took the Grand European River Cruise in May 2014 and loved it. When Viking announced they would be offering ocean cruises we knew we would book one soon!
We explored Venice on our own before disembarkation. It was very simple to access the ship via water taxi from the Hotel Metropole steps from St. Mark's Square.
The cabin was spacey and always meticulous cleaned. Our stewards were attentive and accommodated our every request.
