Get up, gather your belongings, walk away.
Apparently, thats a little too hard a concept to grasp, but in its simplicity, its a definitive answer for a lot of the worlds, ( Disney? ), problems.

They shouldn't have to get up and walk away. They aren't the ones in the wrong. That only leaves the offendors to prey on other people. It isn't simply a case of people being obnoxious, it is a case of people specifically bullying a child. The family had every right to expect Disney to remedy the situation. And as apolice officer, you should know that you have absolutely NO power outside your jurisdiction. You may be able to intimidate offendors, but you don't have any additional authority that an ordinary guest wouldn't have.
