Just got back from our week stay. Right before we left I was extremely worried about this. We had 2 studios (2 adults/1 child & 2 adults) at a DVC resort, the room with 2A/1C had the DxDP. I was armed with my email from guest relations saying sharing was allowed but I never needed it. We had no issue using credits for all of our meals, most servers said we were doing it the "right way" by splitting since it's so much food. At some restaurants we used 3 or 4 credits and at the buffets/AYCTE/Storybook dining we used 5 for the meal. We were also told many times that our son could order off the adult menu. We ate at: Ohana breakfast, Homecomin, Crystal Palace Breakfast, Boathouse, Brown Derby, Trattoria al Forno (character breakfast), Ale & Compass, Artist Point Storybook Dining, STK & Frontera Cosina all with no issue at all.
