I just checked weekend prices for Feb. 07. The cash discount price was about the same as buying points from someone for about $10 point.(If staying on a weekend) It seems that the cash discount is ok for the weekend, but it would be much cheaper to try and transfer points into your account for weekdays.
Examples:
Sat. Feb. 17: Studio at OKW $269 +tax or 27 points
Sat. Feb. 24: 1 Bedroom at BWV(Boardwalk View) $560 +tax or 60 points.
Studio at BWV (Boardwalk View) $322 +tax or 32 points
