The very nature of your question and some of your comments implies to me that you may want to do a lot more research before your sales presentation next year.
Anyone not looking at the resale market given the high costs of points direct is insanity unless you have to finance. If you have to finance, not only will you be paying a premium to buy those points, (more than double in some cases), but you will be paying greater than 10% interest on the purchase. (At least this is what I last saw
DVC was financing at, but in honesty am not in the market for points, so I haven't read many of those posts discussing purchasing to know what the actual interest rate is currently).
That said, you may want to understand the differences in what you can use your points for if buying direct vs resale. Their are restrictions on buying resale, but if you plan to use your points at DVC resorts than it shouldn't matter. If you plan to trade out, it will. My resale points were grandfathered in before the rule changes, so I am not current on the differences.
Since you stated that you go the same time every year, have you considered your use year? Something you may want to research.
Do you care where you stay? If you do, again do some research on the various hotels and decide if going resale may help you get into that hotel since you can easily book 11 months out if you go the same time every year. If you don't want to stay at BLT or AKL you may not want to buy direct.
If you want to stay at VWL, or BCV rather than the resorts they are currently pushing, resale will be a better option.
Lots of things to think about so you can make the most out of your purchase and hopefully enjoy DVC for years to come rather than regret it and be on the resale market yourself.
To be honest, dh and I never took a sales presentation. I did research here on the Disboards and a couple other sites for 1.5 years before we bought resale. You likely will get way more info here on the boards if you ask the right questions, and read the pertinent posts regarding the ins and outs of DVC. We have now owned for over 5 years and have been thrilled with our purchase and hope the same for your family.
