D23, the official Disney fanclub event, is returning to Anaheim in August of 2024. This announcement came this morning, along with a placeholder website re-launch. You can already book your hotel, as well as sign up for updates on when passes go on sale.
The event will take place August 9th-11th, 2024 at the Anaheim Convention Center, next to Disneyland.
It ACTUALLY looks like D23 will be even LONGER in 2024, expanding to an entire week, running August 4th-11th. (At least, according to Collider.)
