we just got back...had the regular DDP last week. Cannot see how you could possibly eat everything on the Deluxe plan, or allow that much time for sit-down meals a couple of times per day! We are not small people, and never finished everything on one table service a day with no appetizers. Didn't finish most counter service offerings, either...the portions are very large.
Kids meals looked to be plenty of food, too (and yes, the "appy" on the little kids' meals is a fruit or veggie, not what most adults would call an "appy", and the "dessert" on a a lot of them is grapes or applesauce. For example, the kids' meal would be mac & cheese (entree), carrot sticks (appy) & grapes (dessert.) I know some kids were complaining that they were not getting an actual sweet for dessert, so some places seemed to allow substituting a cookie for the grapes.
