Hi, I can't believe I am asking this question but can more than one person's credit card be put on a single room? I am taking my parents and two aunts down with me next week and I don't have a problem with my parents but one of my aunts likes to buy a lot and is not a good payer. I would just tell her that the room key is not valid for charging but my mother decided we need the dining plan for the first 4 days at $160.00 a person. I tried a search but nothing useful came up. Thanks for any info.
