When we read that Norwegian Cruise Lines was adding a free Unlimited Drinks package to all 2016 cruises on their Norwegian Sky ship, we nearly fell off our chairs. In general, cruises are notorious for serving over-priced drinks, and the cost of adding a drinks package is often exorbitant. So is this new offer from NCL all it's cracked up to be? Here's what we uncovered. What's the Offer? Norwegian Cruise Line is offering a free Unlimited Drinks Package on all 2016 cruises aboard the Norwegian Sky. (Normally, this costs $69 per day.) The Norwegian Sky runs 3- and 4-night cruises from Miami to the Bahamas, stopping typically in Nassau, Grand Bahama Island, and Great Stirrup Cay, NCL's private island. The unlimited package includes sodas, beer, wine, and premium spirits — aka, the good stuff. Obviously, guests have to be over 21, otherwise the drinks are limited to soft drinks. This package doesn't include tea or coffee, but we think we can make do with a gin and tonic instead. You Could Save Up to $552 on Drinks for a 4-Night Cruise Typically, drink packages on cruises can add significantly to the cost of your trip. NCL's Ultimate Beverage Package usually costs $69 per person per day, so on a 3-night cruise for two, that would cost $414. On the longer 4-night cruise, you would pay $552. (It's worth noting that neither of these include gratuity.) Considering that cruises usually start from $398 (excluding taxes), the free unlimited package could save you over 50% on what you would otherwise pay for the total trip. If you aren't much of a drinker, then the savings are less, but still notable. Nine glasses of the cruise line's cheapest wine would have set you back $58.50 not including tip, about 7% of the average cost of a cruise. But since NCL has included this new feature in the cost of a ticket without raising rates, you're still saving, regardless of what or how much you drink. The Verdict We think this deal is totally worth it, especially if you were already going to buy a drinks package. To find eligible cruises click here, and don't miss our Editors' Choice pick.
