We used to always buy the drink package until we hit diamond. Since hitting diamond, we haven't. With the package we would average 10ish drinks a day. Port days was more of a challenge. My wife and I are both prime in the casino at this point so between those free drinks when the casino is open and the diamond drinks, we haven't purchased the package. Even without the casino drinks, the four free in Port days made it hard to "break even". After the 4 free, you'd be needing likely 13ish drinks per day to "break even" if buying beer and factoring in the first four were already free, or likely 11 if you get mixed drinks. Sea days? Sure. Port days? Tough.
