I tried to get a straight answer Via Online chat, since calling seems to be a nightmare right now. All they said that they could tell me was that Tier II was covered under the dining plan, but they said that's all they could say Via Chat. Nothing about Tier I. It says "select Disney Dining plans not accepted" when I try to book in the upper right hand corner when confirming my guests, but some of the dinner packages say that even if they are accepted under the dining plan. I understand it's probably going to be 2 Table service Credits, which is fine. I planned on Going to Tiffins that day anyway, so it's a bonus for my SO and I. Anyone get a straight answer on this?
