When you are finally approved for financing you will receive a formal letter from DVC. It takes a couple of weeks for that letter to arrive.
With regard to the web site access, if you're talking about being able to enter your member number and receive email notices, it normally takes a few weeks for that to occur. What you experienced were normal delays.
When you're ready to pay off your DVC financed amount, just give them a call and they will walk you through the process. It's not difficult at all, and they are very used to this happening.
