There are two things I would recommend but I am not sure of the correct titles.
First is there is sometimes offered a ship's tour. Get to see everything behind the scene. Given a robe, group picture, personalized stationery, and other goodies. I think we paid $150 each.
Second is the winemaker's dinner. We paid $40 per person and it is well worth the money. You are in a secluded section of the dining room and get a different wine with each course. The head guy gives a talk about each wine and each course. Enjoy!
