It is not often Disney offers the kids sail free promotion. However, the tourism industry is really hurting in Mexico, so I am sure even Disney is having a difficult time filling ships. Per the Disney promotion page, kids 17 and under will sail for free with every two full fare adults. This offer is of course also only valid for sailings out of Los Angeles for 7-night cruises for most sailing October 30, 2011 to December 18, 2011.

Like most things associated with Disney discounts, the real opportunity here is pretty slim. Obviously kids will be in school during this promotion, and they would need pulled from class if going on this vacation.

Make sure to ask for offer KFO to receive the discount.
