Hi,
I would definitely go for renting points. We just returned from OKW, Sunday thru Thursday. We rented for 9.50 a pt, which totalled 522.50. I think it was cheaper than getting a value resort, with all the tax they add! Also, I don't know if it was a mistake, but my room card stated that I was a DVC member. I did take advantage of the 10% discount from several restaurants. (They were listed in the member's packet we got at check-in).
The studio was a good size, and the fridge and microwave came in very handy. Also, it was very quiet. I did not like the fact that you had to take a bus everywhere, the place is huge. We stayed at VWL a couple years ago in a one bedroom. With kids, I liked it much better, since everything was right there. You didn't need to hop on a bus to go up to get supplies, or to hit the arcade.
I was nervous renting from a stranger. I tried to find someone who had a large number of posts. I also reviewed some of their previous posts to try to see if they were honest. I would definitely not rent from someone with few posts, just paranoid I suppose.
We are renting again for a one bedroom at SSR this November. Crossing my fingers that this one goes as well as last week!
Good luck, and have fun. The kids will love VWL!!
