If you purchased the dining package, where does it show up on your itinerary or MDE?
I'm pretty sure it was under tickets. Sometimes it disappeared, but it always came back. It didn't show properly either - should have been 3 adult TS, but showed as 1 adult and 1 child TS, and 1 adult QS. So don't panic if you see something similar!
I rented DVC points, and the dining package and don't see anything at all yet. Hope it shows up soon just to put my mind at ease.
