The itemized bill is by each KTTW card. For my daughter, for example, it was on my master bill but had her name and then not only the things she had charged to her KTTW card but her tips, her excursions, her spa treatment which I had arranged under the blanket reservation. If your mother charges all the drinks, she'll get the bill even if you drink them. If you charge a drink on your card, it will show up under your name on the final bill. Nancy Very easy to know who charged what.
