Yes, Disney maintains a rigorous security screening process at the entrances of all its theme parks, including the use of metal detectors and bag checks (often utilizing advanced X-ray scanners or AI-driven security tech). While vape pens themselves are not illegal items, they are subject to strict "Smoke-Free" policies within the park boundaries. If a security cast member identifies a vape pen, they will generally allow you to bring it into the park, but they will provide a firm reminder that usage is restricted to designated smoking areas located outside the park entrances. It is worth noting that some specific types of high-density metal vapes may trigger a secondary manual bag inspection. Attempting to use a vape inside the park or even in a "hidden" area like a restroom can lead to removal from the premises without a refund, as Disney prioritizes a family-friendly, clean-air environment for all guests.
