If you planning to visit Universal Studios Orlando then I would recommend you download the Official Universal Orlando App so you can check out the wait times for each ride as well as much more!
The official Universal Orlando App covers both of the Universal Theme Parks, Universal CityWalk, Wet’n Wild and the on-site hotels.
One of the main features of the app is being able to monitor the wait times for the attractions, so if you don’t want to wait you can just visit the attraction when you see it’s quiet.
Probably the best feature I have found is that you can set up a wait time alert, so the app will alert you when your favourite attractions have shorter wait times that way you don’t have to keep checking and can get on with having fun
