Just be aware of the tradeoffs:
1) DVC owners often book at 11 months out, so availability can be extremely limited on the highest demand options inside the 11 month window and often a bit limited inside the 7 month window for anything but SSR studios.
2) DVC reservations are usually a "no refunds" policy (as owners may not be able to use the points if you cancel) - so be sure you are 100% on your dates and plans, and strongly consider travel insurance.
3) I also should add that DVC studios (other than OKW studios - which have 2 queen beds) only have 1 queen bed and 1 pullout sofabed. If your kids are little, they might not care, but it's different than the hotel rooms.
