The Disney Dining Plan is offered 'free' only for a certain time and only for a certain number of people.
The great majority of guests who currently use the DDP do pay for it.
Comparision between the current DDP and the changes for 2008 should be done on the basis of a guest who is buying the plan and not getting it for free.
It's hard to argue against free food, of course.
The majority of guests, though, have not been getting free food.
I would rather see WDW use room discounts or upgrades, etc., for promoting attendance rather than 'free' food.
