Okay,
I'll just start.
You don't own a week. You own/buy a yearly amount of points. You receive these points - the amount you purchased - every single year. You can either use them in that year or bank them for the next year or borrow them if you are short on points.
You pay maintenance every year based on the amount of points you own. For example, I own 240 points. Some at BWV (Boardwalk) and some at SSR (Saratoga Springs). So every month above the thousands that I paid for the points in the beginning I pay just under a hundred dollars a month for maintenance.
Then I decide how I use them every year. Sometimes I might use some points to stay X number of nights in a studio - sometimes five nights in a one bedroom. Whatever I choose for my points. Two vacations. One vacation. Three vacations a year. No vacations one year (because I've chosen to bank my points or most likely I've used all my points through borrowing!!!!) All depending on how I choose to use my points - time of year and unit size tell you how many points. Studios cheapest use. Grand Villas (huge) - the most. Christmas the most points. Other times of year not as much etc. etc. etc.
If you're a planner you should buy where you want to stay (from Disney or resale). Because from 7-11 months out from when you're going it's like you have home field advantage. Using me as the example - I would have four months to get the priority at BWV and SSR. And then at seven months out from the reservation it doesn't matter where you own. Me I have only used my "home field advantage" once in five years of ownership. Most people use it though. I'm not a planner.
You can use your points outside of DVC resorts. Most say it's not a good use of your points. But it is an option and I'm sure those who do thoroughly enjoy their trips. Smiling.
So questions?
