Excellent point. Also keep in mind (for those who may be concerned) that unless Disney has recently changed the way they finance, going through them does not effect your credit. Hence, the higher interest rates.There is also the option of financing with a HELOC (home equity loan). Our rate is significantly lower than financing through Disney.
Plus you USUALLY get an equal number of points to be used in the next year. For example, you buy 160, you get another 160 free that have to be used in the next year. We did that when we bought BLT last December. When we talked to our DVC salesman this December, we talked about adding on 50-100 points, and he said whatever we added, we would get a matching number free for the next 12 months. Only thing was they wouldn't finance 50 points. They will finance 100 points and above.
