The number of points you purchase will depend on the size of the unit (studio, 1 Bedroom, 2 Bedroom or Grand Villa), the time of year you plan to visit, the length of your stay(s) and as Rich said, the $$$ you can afford.
Disney is currently selling HHI, VB and VWL. OKW and BWV are available via resale only. BCV are rumored to become available sometime late in 2002.
As an example, if you planned to vacation in Adventure season (January, September or first half of December) at OKW in a studio, point requirements would be:
8 for each Sun - Thur night
20 for each Saturday & Sunday night
80 per week
At VWL, the points for the same vacation would be:
12
22
104
Larger units require more points as do other times of the year.
If you would like to give us more specific information regarding your vacation plans, we can be more specific about point requiremetns. In the meantime, there is a lot of great information here on the
DVC board. We found it invaluable in making our decision. Good Luck on making yours - whatever it may turn out to be.
