You can use points at any WDW resort except the Value resorts or any resort which also has an included DVC resort (WL, BW, BC)
For 2005, points per night range from a low of 15 pts (Weekday, Standard View, Caribbean Beach, Coronado Springs, or Port Orleans), Value Season (Jan 1-Feb 16, Aug 28-Sep 28, and Oct 30-Dec 19), to a high of 173 pts for one night at the GF, Concierge, weekend night, Holiday Season (Dec 20-Dec 31).
For each resort below, the 1st number is the lowest point (weekday, lowest room view, value season) and the 2nd number is the highest point (weekend, highest category room offered, holiday season). All other combination are in between.
GF: 39/173
Poly: 35/140
YC: 34/139
Contemporary: 28/99
AKL: 29/128
Ft. Wilderness cabin: 27/68
CB, CS, and PO: 15/43
You can pretty much bet that for 2006 the points will be higher.
