They will scan all your luggage before it makes it on the boat, as well as what you are carrying on. They will have some great deals on booze while you are on the ship. The bad part is, they keep it for you until the end of the cruise. I got 4 bottles of Bacardi for my wife at 10 bucks per bottle.

If you are really good, I mean really good at picking out real cubans from fakes, you can find some on your trip. But even then, it may be fake. Cozumel is supposed to have an LCDH. Do a search for it. Otherwise, there are fakes abound. Glass top boxes a plenty!

At a couple of the main restaraunts like carlos n charlies and Senor frog's, they do have small humi's with some real cubans, but way pricey. I paid 16 bucks for a Monte #4. On the beach, everyone has cohiba's, so watch out. Your cruise ship will have one brand of cubans on it, the best you will get is a Guantanamera.

It depends upon the cruise line; Disney allows you to bring alcohol on board:

Bringing Alcohol aboard the ship

Alcohol is permitted on board. Any fragile items (including bottles of alcohol) must be brought aboard in a carry-on bag not to exceed 22" wide, 14" high and 9" deep. All fragile items must be transported inside carry-on luggage...

I am unclear on your question. Your original question appeared to be about smuggling alcohol into the USA. Now are you asking about smuggling wine out of the country? :tf

Re: Alcohol on the cruise...
 

I think he is (now) talking about smuggling alcohol onto the ship in the US so that he does not have to pay shipboard prices for alcohol.

As for bringing alcohol on board in a port-of-call, I believe that most cruise lines will let you buy alcohol in a port to bring home, but I only know for sure about Disney -- and they will let you do this.

Re: Alcohol on the cruise...
 

If I remember correctly, on Royal Caribbean and Celebrity you are allowed to bring on 2 bottles of wine but no hard liquor. Don't forget to take a cork screw with you otherwise there is a crazy corking fee. Like many people have already said, anything you buy while on the cruise they will hold on to until the end.

Well Bob's post is technically correct. Cruise ships are registered in countries with flags of convenience. The minute you enter a cruise ship you have left the United States. :tu
