We just got back yesterday, and here's what I encountered:
Specialty drinks are not included, and that includes the smoothies at Le Cellier, glowing ice cube drinks at 50's PT, Sci Fi, etc, any drink that comes with a souvenir mug.
At 50's PT, the milkshake is considered dessert - so if you still want dessert, I suggest paying OOP for the milkshake.
Specialty coffees, like cappucino, lattes, etc aren't included. The regular coffee is included.
At Pepper Market (CSR) the only thing you can get for dessert is the muffin or cookie.
At POFQ food court, you can get the 6 piece beignet as your dessert.
At Main St Bakery, you can get any 2 items + a drink (any drink - powerade, milk, juice included)
At Sunshine Seasons (the Land, Epcot) the drink item is a medium sized (don't get the large cup)
The
DDP was fun! It was fun being able to just order anything you wanted and not think about it.
