We ended up buying from a broker. We had our hearts set on BWV. We did not want to buy anywhere else. The deals for AKV at the time we bought did not appeal to us as we do not want to stay there. We were also able to afford the resale more than directly through Disney (Disney offered BWV to us for $104/pt., min. 160 points). We ended up with a 150-point BWV contract for $81 per point. Significant difference!
We did not have any problem waiting to get what we wanted. We just went to WDW in July and are not planning to go back until summer 2010. That's why we got
DVC, so we can go every other summer for nice long trips and afford large accommodations and walk to 2 theme parks! So we were willing to wait a while if necessary. Something came through very quickly for us. We originally requested a March Use Year but then we realized April would also be fine for our travel patterns. I called **** and told him April is fine also, and got a call back literally within minutes from him that something was available! And that was it...we told him what we wanted, he found it and advised us on our offer, we made the offer, owner accepted, Disney passed it, and then it took about 3 weeks or so from that point to close.
Like I said, we had time. Some people buy with the intention of using the membership right away or within a few months and so they do not risk resale. Some people also want the latest resort and can get incentives through Disney whereas they can't with resale if it is even available.
For DH and I, there was no benefit by buying directly through Disney. Resale worked better for us and saved us around $4,000 than if we had gone directly through Disney.
