There are lots of ways to take advantage of Genie+ services.
Disney replaced its old free FastPass system with Genie+, a paid service available on the Disney World and Disneyland app.
I think the Genie+ user experience can be difficult to navigate, but it’s awesome if you’re trying to get on as many rides as possible.
Genie+ allows you to book Lightning Lane reservations for specific attractions throughout the day. When it’s your reservation time, you simply scan your ticket or Magic Band at the Lightening Lane entrance and skip the majority of the line.
If it’s your first time using it, I recommend watching a few videos about Genie+ ahead of time so you can make the most of your day.
