We just got back from a wonderful Disney vacation! I've been trying to talk DH into buying through
DVC for years, well after this trip he is finally very interested

We really wanted to make time to meet with a DVC sales representative but we just couldn't fit it in our week. Anyways we have some info on buying but we are a bit confused. We would want to buy for the first week of May, in a 2 bedroom at either a standard view at BLT or a savannah view at AKV. According to the chart someone gave us it says we would need 317 points for those resort rooms. How does this work exactly? Do I buy by point and the property? I know there's annual fees but other then that how do I know how much I would need to finance when I purchase? And our the points in addition? Thanks for any info
DVC works on a points system. You purchase a certain number of points. Every year, get that same number of points and pay an annual Maintenance Fee (MF) on those points.
Yes, a 2-bedroom villa at AKV (savannah view) or BLT (standard view) both happen to be 317 points per week in May.
If you purchase directly from Disney, 317 points at AKV would cost about $42K to purchase, or about $130/point. With a little diligence and patience, you probably could find a DVC resale for AKV for under $75/point. For direct or resale, every year, you have to pay the MF. In 2013, this is $5.67/point at AKV.
BLT is more expensive. Direct price is $165/point. Resale is around $100/point. BLT's 2013 annual MF is $4.50/point.
MF typically increases in price 2% to 5% every year.
I suggest you read here for an intro to DVC:

Lots of people finance but, ultimately, DVC is about saving money. Financing your DVC will erase most of any savings you might realize by buying.
Instead, if you are looking to vacation at WDW and save money while staying at a Deluxe Resort, then the best way to do that is to rent DVC points. David's
DVC Rentals is probably the best known.
Be sure you learn as much as possible before making any DVC purchase!
