None will. Substituting an appetizer for a dessert on the basic plan is not permitted under any circumstances.
All this year I have seen only one poster who said they had success getting an appetizer - and it turned out they had checked in prior to January 1 and were still on the 2007 plan.
There are only a couple of ways to get appetizers on the basic plan - book fixed menu restaurants like CRT or Ohana that include the appetizer in the full offering, or book the Fantasmic Dining Package at Mama Melrose or Brown Derby.
