I'll tell you what I know although I haven't used them. You can go to the Carnival website and order them. I've read mixed reviews on them on this message board. Some folks say that they save a little bit of money on the more expensive drinks and that they are very convenient. Others say that they weren't worth the little bit they saved and that some waiters wouldn't let them use them on the frozen drinks - only on bar brands. I'm going the route of taking the mini liquor bottles on board with me to save the money. I've heard all kinds of stories about taking your own water, alcohol, and soda on board. I'm going to give it a try in early August on the Paradise.
