Ok...here's a breakdown using the charts from 2005...
Disney's Beach Club Studio Sun - Thurs 12 pts./day Fri-Sat 22 pts/day
Grand Fla Gard. View Sun - Thurs 39 pts/day Fri-Sat 70 pts/day
AKL pool view Sun -Thurs 29 pts/day Fri-Sat 70 pts./day
So if you stayed in a Studio at the Beach Club in January for a full week it would come out to a grand total of 104 pts, but if you stayed at the Grand Fla in a Garden View room for the same week it would cost you 335 pts, and AKL in a Pool View room it would cost you 285 pts.
Keep in mind this is Value Season, using the most standard rooms available...go during any other season or upgrade your room and the points go way up. (Grand Fla Holiday Season same room cost for the week 516 pts., or the same value season week for Concierge level costs 577 pts. at Holiday this concierge would costs 826 points) and the Beach Club would be 181 pts. for the holiday week.
Hope this answers your question, and why DVC'ers don't ususually use their points when staying in a non-dvc hotel and they also go off property for Fri and Sat also!
