I'm going to go against the grain here and support what BDE has said. Disney Financing is very painless, fast and seamless. Do they have higher rates than the other companies? Certainly, but sometimes the benefits outweigh paying a little more.
Before we dwelve into what paying a little more means, the benefits: They give you your points to use asap, no waiting and wondering while ROFR and closing goes on. The payments can be tracked on your
DVC membership site. Never have I heard of a clerical error through them, although I'm sure it happens with every company once in awhile.
Paying a little more: Interest rates, I'm not about to go into the math. Lord knows I get enough of that in my job. But, if you plan on paying it off within a few months, the difference will be quite small, and well worth the convenience. We all know the smartest thing to do when buying a luxury is to pay cash, so one could argue that anyone financing is playing the part of the fool.
(Question to myself: Was I a fool? ... <time to recall my thinking back then>... Answer: Nope. I was determined to take a yearly trip with the kids to WDW anyway, and the cost of a timeshare, plus interest over the 14 months I paid it off still worked out to a deal compared to WDW's normally discounted rates at the moderates, takign into account that I will own the DVC for 50 years total and will stretch it out as much as possible by booking studios.
Now, lets talk about owning at higher fee resorts... because when it comes down to it, that's where our money goes regardless of what price we buy in at.
