i have always carried soda and 2 bottles of wine in my carry-on and taken it too my cabin. no questions asked. i am going to pick up a 12pack of beer this next cruise and see if i can get it too the cabin also ( i will put this in my checked bag ). i think as long as you dont try to take a excessive amount you might get lucky. im sure others here will be able to give you better quantity amounts that are safe.
We always bring on 4-5 bottles of wine on board and haven't had any problems. We started doing this after I first cruise when we paid $75 for a bottle of wine that we can buy at home for about $30! We bring our bottle to the dining room and they will serve it with our dinner. I think they charged us a $10 corkage fee. We enjoy good wine with our dinners and have found that even with this corkage fee, we are able to enjoy a nicer bottle of wine for a much lower price.
Sure the alcohol will cost more in a restaurant than from your state store (as we have in PA) or your convenience store back home. Why is that justification for bringing your own on board. When I dine at a nice restaurant or join friends at their country club should I sneak some bottles of wine or liquor in with me because "the prices are so high?" Perhaps I should bring my own food along as well.
No need to sneak wine on board. Carnival does allow you to bring a couple of bottles. From their website:
Fine wine or champagne may be brought on board during embarkation only. If the wine and/or champagne is brought to the Dining room for consumption, a $10 corkage fee per bottle will be charged to the guest; otherwise, the guest may only drink the wine and/or champagne in the privacy of a stateroom.

Our TA had a 2 bottles of wine in our cabin upon our arrival. We brought one to dinner and were NOT charged a corkage fee. I thought that was a nice gesture on CCL's part. Perhaps it is up to the individual waitstaff?
