I just checked with Disney and you cannot "rent" the castle. Your family has to be chosen while you are in the park, which kind of stinks. If you are leaving that day and are chosen to stay in it that night, do you change your plans or pass. I think if you were flying out that night, it would be difficult and expensive just to stay in the castle. If you lived close by, that is another story. I wish they would make it available to rent, I think a good number of people would be interested.
