Which of the following is a common prohibited behavior in Disney parks?

Fighting, harassment, and drug use are considered common prohibited behaviors in Disney parks because they compromise the safety and well-being of guests, cast members, and the overall atmosphere of the parks. Disney has established a family-friendly environment, and any actions that can lead to physical harm, intimidation, or illegal activity are strictly prohibited. Ensuring a safe, enjoyable experience for all visitors is paramount, and behaviors like fighting and harassment violate this principle. Additionally, the presence and use of drugs are against the law and, therefore, not tolerated in any setting, especially in a family-oriented environment like Disney parks.

Other behaviors listed, while sometimes regulated, do not carry the same level of immediate risk or threat to safety that violent and harassing actions do. For example, walking in designated staff areas might be prohibited to maintain operational integrity, but it does not create an unsafe environment. Similarly, outside food and drinks might be restricted for various reasons, such as park policies on cleanliness and food safety, but they do not pose a direct threat to anyone's safety. Requesting photo sessions with cast members is generally permissible, as long as it's done respectfully and without causing disruption.
