just the deposit has to be paid on the disney visa. $200.
You have to pay it off by 45 day mark before trip date.
Yesterday, the CM first tried to tell me that the balance had to be paid using the same credit card (the disney card). I said, "could ya go and check that please" - she came back and said I was right. Uh yeah, I know cuzz my Dis told me how it works (yay Dis!).
You can pay the balance any way you'd like. check, (any) credit card, whatever.
Also - as far as the 0%. I was told here, that the 6 mos 0% interest on the deposit is from the day I put the deposit down on the disney credit card.
Now, if I pay the balance later, say at the 45 day mark or whatever, the 0% interest would start from that date (not the day I paid the deposit).
Does that make sense? Hope that helps you!
There are a lot of threads on the Resorts/Codes board on the Dis regarding Disney Visa and
Free Dining that helped me out a lot (thanks knox and gang!)
