Ok so I keep reading here (and on the rest of the internet) that child QS credits can be used to purchase adult meals, and that this is now officially "allowed". And that it's officially allowed to pay for non-DDP guests with your own credits.
But I can't find anything on Disney's site to corroborate. Their 2017 pamphlet specifically says the opposite.
We're considering adding the QS plan to our room (2 adults, 2 kids under 9) and sharing the credits with my mom, who's in another room. We can't use enough QS credits to make the plan make sense on our own, but if we split them with her the math is good because we can use the credits selectively at the more expensive restaurants.
Is there anything anywhere that actually spells out the new rules?
