Can I visit all of Universal Orlando’s parks with a Halloween Horror Nights ticket?

A Halloween Horror Nights ticket will only grant you access to the event itself. You cannot visit Universal Orlando’s other parks with a Halloween Horror Nights ticket. Although the event takes place at the Universal Studios Florida park, you will not be permitted to enter that park until the event officially begins. A Scream Early Ticket is available, which can be purchased in addition to a Halloween Horror Nights ticket, for early entry into the Universal Studios Florida park. Otherwise, you must purchase regular theme park admission to visit Universal Orlando’s parks during regular operating hours.
