You must join a Virtual Queue to experience Bluey's Wild World (and the Wildlife Express Train and anything else at Rafiki's Planet Watch). The queue "opens" in the official Disney World app at 7:00am and 10:00am each day, and we expect spots to go quickly. When your Boarding Group is called, head to the Wildlife Express Train Station in Africa to start your journey. Because of the train rides involved, you're committing a good chunk of your day (at least 90 minutes) to Bluey if you choose to experience her Wild World.
