The app is terrible. The idea is nice, but it's slow, non responsive, not at all user friendly, the in park navigation is absolutely horrific, Genie+ only allows 2 rides per day, but most rides don't offer a Genie+ later in the afternoon. It's a necessary evil if you're doing a long vacation stay like we did, but if you can enjoy the parks without the app then please do so. The app was the only part of our vacation that was irritating.
