You no longer need to be escorted into Star Wars: Galaxy's Edge by the First Order with a reservation because it's officially opened to the public. Everyone is going to be rushing to Disneyland to check it out, so if you want to visit Batuu then you have to act fast.
Disneyland is going to use a virtual queuing system through the Disneyland app or kiosks throughout the park that will act like a Fastpass.
You'll be assigned a boarding group with a two hour return window to come back throughout the day.
This is perfect because now you don't have to waste your time at Disneyland standing in line all day long, but instead you can enjoy the rest of the park. Once it's your turn, you'll get a notification through the mobile app or digital signage around the park to let you know when it's time. Once you're in Star Wars: Galaxy's Edge you can stay in as long as you want!
