For the WDW
DVC resorts, weekday nights (Sun - Thu) are one rate and weekend nights (Fri, Sat) are another, higher, rate. For example for the dates you mention, to stay in a studio at BCV would cost 14 points per night for each weekday night and 32 points per night for each weekend night. For convenience, the charts also list a weekly rate which is 5 times the weekday rate plus two times the weekend rate for this room type. For example, for the BCV studio for your dates the weekly rate is 134 points which is equal to 5 times the weekday rate of 14 pts/night plus 2 times the weekend rate of 32 pts/night.
Hope that helps clear up the confusion!
