"Now in 2023, we’ve heard rumblings that Ariel is coming back to the Magic Kingdom. While not yet confirmed by Disney, we have heard this location is expected to open within a month."
"At the time of this article, Disney still lists Meet Ariel at Her Grotto as temporarily unavailable. There is no listed return date or additional info about the offering, but, we expect to see this change in the coming weeks if the rumors are true."
In MDE, the calendar does show that this attraction having times (12:00 AM) starting tomorrow. Obviously, that's not the right time. This might be heating up.
