We were recently on the Norwegian Sun and purchased the upgraded package. We found it worth the money because we could drink bottles of 'Moet' and 'Pommery Rose' for lunch and sometimes dinner and order 'Veuve Clicot' champagne by the glass at the Champagne Bar. Other outlets on board, other than the two main dining rooms didn't have the champagnes. Wines were more challenging as we mainly drink White or Rose rather than red. The '6 Sens' rose by the glass was pale, dry and palatable whereas I opted for a white wine from the basic package but I could order it by the bottle rather than the glass which I like. We also ordered a bottle of San Pellegrino sparkling water with lunch and dinner so all in all, I felt we had good value for the Plus package and the extra we paid.
