Yes, we went last month with 5 adults. Three of us had separate credit cards attached to our KTTW cards and the other two didn't use their KTTW cards for charging. We were all in the same room. Two notes though: 1) I'm pretty sure that you have to have at least one credit card on file and 2) make sure you check out the bill at the end of your trip to make sure all the charges went on the correct cards. Even though my BIL's personal credit card was attached to his KTTW card, mine got charged for his charges at the end of the stay. It was easy enough to add his up though, and he just wrote me a check.
