We bring a bottle of 'Fairytale Cuvee' Champagne home from Florida to North Dakota every year. We just pack it in some bags and pad it with sweatshirts and clothes. It has never been an issue on the plane, however, we cross our fingers each time. Is that what you mean?
My sister-in-law brought homemade 'Red Eye' (which is liquor drink) to The Caribbean Beach Resort for our wedding and we drank it at the pool there. She packed it the same only put it in a plastic bottle and labeled it with all of the ingredients (in case it got searched at the airport).
If nothing else, they sell wines, beers, and all sorts of liquors at the Disney hotel shops (for a larger fee of course, but not TOO terrible).
Hope that Helps!
