BTW just to post the slightly different response I just received (word for word copied in):
We regret the disappointment expressed in your email. It is not our intent to upset our loyal
Disney Cruise Line Guests.
Please allow me to explain. We regularly evaluate our policies and procedures and it is true that we have recently changed our alcohol beverage policy to limit the amount and types of alcohol Guests may bring onboard in our home- and out-ports.
For the sake of clarity, as you probably know, effective for cruises embarking on or after September 30, 2015, Guests 21 years and older may bring aboard a maximum of 2 bottles of unopened wine or champagne (no larger than 750 ml) or 6 beers (no larger than 12 ounces) in their carry-on luggage at the beginning of the cruise and at each port-of-call. This type of alcohol beverage policy is not unusual in the cruise industry.
Additional information on our policies can be found on our website at:

Though it may take time for the input we receive to be fully assessed and acted upon as a whole, please believe that we are seriously committed to, and diligently working toward, providing our Guests the kind of magical vacation they have come to expect from Disney. We will continue to strive to provide our Guests with the finest vacation and entertainment experiences, and we are very grateful for your valuable input to help us achieve that goal.
We hope these concerns will not affect your regard for Disney, as there is magic in the Disney name.
