Until the revised alcohol policy, I had always had wine and spirits in my checked bags on
DCL without incident. The alcohol was never confiscated in 21 previous cruises. So the concern about a "mess" was not an issue during our previous 21 cruises over 17 years, so it must be something more than just a concern about broken bottles or spills. If that were truly a concern, DCL would, it stands to reason, ban any and all liquids from checked bags, which they do not. Non-alcoholic beverages in breakable containers, including but not limited to bottled water, juices, shampoo and body wash, are certainly allowed. (As an aside, although the picture you shared is certainly daunting, although we may have been lucky, we never had a broken bottle on any DCL cruise in the past. Maybe it's a testament to my packing ability, or at least my Costco luggage!)
