Carnival Cruise Lines, which is testing a single-priced all-the-alcohol-you-can-drink package on some of its ships has decided that an “all the alcohol you can drink” policy on a ship crammed with 2,000 sunburned Milwaukeans (or whatever) is probably not the greatest idea.

They’ve put a 15-drink-per day cap on the program (yes, that’s per person), which limits people to 15 (15!!!) drinks in a 24 hour period from 6am to 6pm.

No idea how they decided 15 drinks is acceptable while 16 is not, but that’s something to keep in mind on your next cruise.
