Universal's Halloween Horror Nights (HHN) 2026 follows a strict code of conduct to ensure guest safety during this separately ticketed event. No costumes or masks are typically allowed for guests to prevent confusion with the "Scareactors" (though rules can vary slightly by location, masks that obscure the face are universally banned). The event is recommended for ages 13 and up due to its intense graphic nature, though younger children may attend at a parent's discretion. There is a "No Touching" rule: while Scareactors will jump out and startle you, they are forbidden from making physical contact, and guests are strictly prohibited from touching the performers. Prohibited items include weapons, large bags, and outside food or drink. In 2026, many parks utilize a "Stay and Scream" holding area for daytime guests, allowing them early access to select houses. Be prepared for metal detectors and bag checks. Most importantly, follow the directions of the "Scarebase" staff, as any harassment of performers or disruptive behavior can lead to immediate expulsion from the park without a refund.
