If you book a package that is under a code, not a DC package discount, than you have to pay 45 days in advance in most cases. I'm a DC member and I booked a DC discount package first. Than when the discount codes came out, I called back and booked using the code through WDTC and the payment policy changed. So it depends on what type package you book what type payment policy you will be under. Even though I'm a DC member, once I used the code from mousesavers, the payment policy was no longer under the DC policy. The only way to get the DC payment policy is when booking a DC package. According WDTC, they are booking all packages. But WDTC is so messed up right now because of all the new policies that this may or may not be true. I would check mousesavers for the latest on payment policy.
