We called about this deal cuz we had already booked when we found out about it. We are in a state that does not allow incoming wine. We are going to call back and see if we can have it sent to a family member in a state that can receive it. Also, a rep told me we could participate in everything with the exception of the dinner they are having without joining the wine club. I am not sure at this late date we can get the $50 stateroom credit.
Let's see: $29+ per month for two bottles of wine in exchange for wine tasting and two top of the line wine glasses. We will do it if they can ship it to a boardering state where fm lives. We can not get good wine in our state. We travel and always bring lots of wine home.
The best thing to do is call them! I don't know anything about the quality of the wine they send. I am thinking this is a first for Carnival.
