They kept a 6 pack of Zima at the pier a few years ago while trying to carry it on. We since put it in our checked luggage, no problem. They tried to make us check a couple bottles from St. Maartin till the end of the cruise last month. I sweetly asked the desk guy on the gangway, why, for just a couple bottles, to which he replied, aw, just go ahead. Luck of the draw ;0)
