We love Copper Creek and it's mostly where we want to stay. That's why we have 3 CC contracts and are currently playing ROFR roulette to obtain more. We also love Hilton Head so picked up a resale contract there last year. Basically we buy at our favorite resorts and love knowing we can get in a 11 months. If we want to check out another resort, we might switch at 7 months if we can, but if not we love knowing we have a reservation at our "home". We tend to travel popular times (Fall, Christmas), and we don't like split stays. So we might not be able to switch at 7 months, making the "buy where you want to stay" advice even more important to us.
Now ...... Poly2 has me pulling back a bit on the additional CC points we buy. We love that resort but don't like studios so we've never considered buying there. Assuming speculation is correct and Poly2 will have 1, 2, and 3 BR villas, we will probably add on there. But that's it. Three home resorts are plenty for us. While we like the other resorts, we only want to own at our favorites.
