Park Services All visitors must pass through metal detection before experiencing CityWalk or the Theme Park. All bags, backpacks, purses, packages and items are subject to X-ray and/or additional inspection prior to entering CityWalk or the Theme Park(s). Suitcases and bags with wheels are prohibited.

Pilots and air traffic controllers use the term "Niner" instead of "Nine" to ensure absolute clarity and prevent miscommunication over the radio. In the ICAO Phonetic Alphabet, established in 1955, "nine" was identified as a potential source of confusion because it sounds identical to the German word "Nein" (meaning "No"), which could be catastrophic in a high-stakes aviation environment. Furthermore, over static-filled or low-quality radio transmissions, "nine" can easily be mistaken for the number "Five" (pronounced "Fife" in aviation speak). By adding the extra syllable to make it "Nin-er," the word becomes distinct and unmistakable to the listener, regardless of their native language or the quality of the signal. This standardized pronunciation is part of a broader set of linguistic rules in aviation—including "Tree" for three and "Fower" for four—designed to minimize human error and ensure the safety of millions of flights every year by using a clear, universal "Aviation English."

Yes, Universal Studios (at both the Orlando and Hollywood resorts) performs a mandatory security screening of all bags before you are allowed to enter the theme parks or the CityWalk dining and entertainment district. In 2026, this process has become highly efficient through the use of Advanced Evolv Scanners, which allow guests to simply walk through with their bags without needing to stop and unzip every pocket. However, if the scanner detects a "prohibited density"—such as a metal umbrella, a large camera lens, or a suspected weapon—a security officer will pull you aside for a manual bag inspection. Prohibited items include all weapons (knives, firearms, mace), alcohol, illegal substances, and "hard-sided" coolers. You are generally allowed to bring in small "soft-sided" coolers with water and snacks, but glass containers are strictly banned. Additionally, Universal utilizes "X-ray" machines for smaller items and handheld metal detectors to ensure a safe environment. This security perimeter is located before the "ticket tapstiles," ensuring that the entire resort area is a secure, monitored zone for all guests and employees.
