Jim Lewis, the head of DVC, gave a talk on the DVC members cruise.
He was asked this question and he said that it requires changes to the computer system. A project is currently underway to make these changes, it is happening.
They hope to announce a timeframe of when it will be available by the end of the year (The announcement by the end of the year, not the meal plan).
He emphasized that it is not a matter of 'if' but of 'when'.
