As far as payment methods, some owners do a three way call with Member Services so the renter can use their Credit Card, but you'll need to trust the owner, as they will also be onthe line. Other people will send the owner Disney gift cards equal to the cost of the DDP. Or, the owner may agree to accept a check with time to allow it to clear the bank before they call Member Services. The requirement to pay the DDP when it is added was effective with a Disney reservation system program update in late 2010.
