But you do know the Dining Plan itself is still available, right? The "free" promotion was for a limited period, but the MYW Dining Plan has been in effect since the beginning of 2005. It's currently $35 per night for adults and $10 per night for children 3 - 9, going up $2 per person per night in 2006.
It's available only as part of a package. What makes a package? Your Disney resort stay combined with your Disney ticket purchase. While you DO have to purchase the dining plan for the same number of nights of your stay, you only have to purchase a one-day ticket for each member of your party to make it a "package".
