I'm jumping on this too and hoping someone can help me figure out a few things. For example snack credits. When looking at the menus online many items have a UD next to them. But it doesn't differentiate if that's an entee UD or a snack UD. Sure in most cases it's pretty simple/obvious. But others - not so much. If an item is 9/10 dollars that would be a fantastic use of a SC, but a horrible use of a meal credit. Any up to date lists out there?
Also some menus, like in the wizarding world, don't have any UD symbols at all. But I know they take it. It's very frustrating. It's almost like they purposefully make it confusing.
