We own at BWV, OKW, and SSR. Love them all.
We bought BWV for the location and the STANDARD POINTS rooms.
We bought OKW for the lower points per room, the lower maintenance, the spacious rooms, and the 11 month window for the GV's.
We bought SSR for the longer end date and the awesome developer incentives at the time.
Here's MY advice, based on how I've been using my points. I HOARD my BWV points like crazy as if they were made of gold.
When I make std view BWV reservations at the 11th month mark and "think" about changing them at the 7th month mark, I scratch my head because while all the other locations are great too, why would I spend MORE points to move AWAY from the BWV?
If I book an OKW reservation at the 11th month mark, I am usually open to switching at the 7th month mark but would not be disappointed at all if we don't switch. The points are so much lower for the whole stay, the one bedrooms are sooooo spacious and it is soooo relaxing on that balcony. The only thing is that I would prefer to have a car when staying there. Ever since DME started, I've been traveling w/o the DH and the car rental so we havent been back in a while.
SSR is a beautiful resort also and I have no qualms staying there. However, I have no problems switching out at the 7th month mark either. The slightly lower points aren't incentive enough to make me feel bad about giving up my 11th month reservation. I KNOW that I will have ample opportunities to stay there in the furure. So, I do tend to try to "use up" my SSR points first and usually don't my 11th month reservations here.
If we didn't buy SSR yet and AKV was an option, depending on the incentives, I think I would have learn toward AKV only because of the 11th month window. There are prime units at AKV that are popular and more easily booked at the 11th month mark. Whereas, all the units and point tiers are the same at SSR, KWIM?
Good luck with your decision!
