All I can say is that our official policy in this forum is to support the cruise line rules. Carnival allows one 750ml bottle of wine per adult to be brought aboard at embarkation. Anyone doing more than what the rules allow is doing so at their own peril.

It is also our forum policy to close threads once the question is answered, or if the thread is likely to invite suggestions on ways to break the rules. So I'll close this one before it gets into the badlands.
