We just got off the Mariner. We bought a 7 bottle diamond package that came to $ 27 a bottle. We bought it on the first day of the cruise, as they said it would only be available for purchase on that first day. We ran out of wine in the middle of the cruise and bought a 5 wine package for the same $ 27 per bottle price. We liked a particular champagne and a red wine. Both were on the wine list for $ 38. So that saved us $ 11 a bottle.
