We have done this with a zipline of Disney characters from one adjoining room to another, but only on the Wonder. Our string was about six feet long. Using magnets we even attached the line to not just the door frame, but the ceiling and walls, too. In the three times we have done this,
DCL has not said a word. Our last extravaganza was a battle across the lobby of the forward elevators on the Wonder. Our son had the same opposite stateroom across the ship from us so we had a pirate sea battle with firing canon and Barbosa on one side and the same with Jack Sparrow on the other. Using Styrofoam balls cut in half, cotton and pipe cleaners we fought for six days along the Mexican coast with no defined winner. I even thought it would be cool to hang "cannon balls" across the lobby ceiling, but thought that that might be too much for DCL. Attached is a sample of our zipline.
