Here's another, kind of simplified, way to look at it.
I bought into VWL when it was first being sold. I became a part-owner at VWL, so that's my home resort. I share my ownership of VWL with the thousands of other people who bought points there - that's the "share" in timeshare. All of us VWL owners together share the operating costs of the resorts; things like property taxes, insurance, utilities, housekeeping, landscaping, etc. That's where your annual fees go.
I don't own a particular unit at VWL. My share of ownership in the resort is represented by points, which I then use as a kind of currency to pay for my stays. Each
DVC villa "costs" a certain number of points per night, depending on the size of the room and the season, and sometimes the view. You decide how many points you need for your vacation plans, and you're charged by the point for your purchase. Your annual fees are also charged by the point. So, people who own more points own a bigger stake in the property, and pay a bigger share of the costs for its upkeep. I purchased 150 points at VWL, so every year, I have 150 points to use for my stays.
Since I own at VWL, I get a home resort booking priority there. I can use my points to book VWL rooms at 11 months out from my travel date. I can use those points for other DVC resorts at 7 months out from my travel date.
Hope that helps a little!
