I have always brought my own wine on the ship to enjoy for a corkage fee at dinner. Never sailed on Royal Caribbean before. I see no declaration regarding this. Will be sailing in 2 weeks . I know alcohol is not allowed but wine has always been under a different catagory.
We just returned from a Royal Carribean cruise last Sunday. Sailed from Ft. Lauderdale. They won't allow you to carry any wine on board at all - for any reason. Also check all checked in luggage and confiscate all liquor. They call the passengers down to get the luggage they suspect is carrying liquor. One man had a bottle of water and they even took that. It was still sealed. They do return it at the end of the voyage ( at least for now). Hope this helps.
