The rides that are open during Halloween Horror Nights vary depending on the location. At Universal Studios Hollywood, the Jurassic World – The Ride and TRANSFORMERS: The Ride-3D are open during the event. At Universal Studios Florida, the park generally closes at 5 p.m. for those not staying for the event, but Hollywood Rip Ride Rockit, Revenge of the Mummy, and Harry Potter and the Escape from Gringotts are open during all HHN events. At both locations, some rides have little to no wait time during Halloween Horror Nights, but in the daytime, these rides can post long wait times all day.
