NWR: Disney Vacation Club

I know I'm crashing but I know there are a lot of Disney girls on here - so i figured I'd ask...
Have any of you ever rented DVC points to stay in one of the villas? Even though I've already booked our anniversary vacation, I realized I could save a ton of $$ by doing this...
So I'm curious to know if anyone has done this & if was a good/bad experience.

Thanks girls!
