I posted that as a reply to someone who said they may not open by the end of the year since we have not seen ADRs yet. New WDW restaurants (not the ones that are just “rethemed”) don’t always open ADRs before the restaurant opens. Often they open and run it without ADRs and then open ADRs. This allows them to work out some kinks without a full house, etc. Recently, that’s how Takumi Tei went. But also I remember back when both Skipper’s Canteen and La Hacienda opened, they both opened without ADRs until they worked out kinks and then they opened ADRs.
Edit to add: We won't know how it will happen until they announce an opening date. At that time, they'll likely let us know if and when they will start taking ADRs. They will need to get their
MDE page up and running, so it will not be a sudden thing. We'll see the page "there" before the ADR dates go live.
