I think they were gonna put it all on the credit card and then make the payment all at once. (is that correct?) The strategy being to collect a bunch of rewards points then pay it all off in a single payment.
I am not a authority on credit cards. I have been told however that even exceeding 33% of your credit card limit in a payment cycle can have adverse affects on your score. I say this only as a comment that may be TOTALLY false. I am trying to recall who told me that. You may want to call your credit card company and ask them about that.
Agreed about not depleting your cash reserves. We have alot of cash we are saving for our eventual purchase and while it was tempting to pay off my wifes student loan, we are just making large chunks each month.
