We are going on our first DVC vacation to BLT in 17 days. We are also doing the DDP for the first time. When we made our res. they said we pay for DDP when we check in. We would like to do the online check in for the first time also. Do I pay for my DDP when I do online check in, or when I arrive at BLT? I guess that is only one question. I hope it makes sense.
