Actually, we ran into problems with that last January. My DD and her boyfriend gave the info, however, it was all charged on my account. On your KTTW, it will list the people as 01, 02, 03 etc. and keeps track as to what each number charges. At the end the kids had to go down and put their charge cards down on their number. It worked ok but was hoping that they could use their own charge cards from the start.
