I also added on 150 points today.
We're splitting it via 100 and 50 point contracts, to increase point options if we decide to sell just one later. I've been wanting more Grand Floridian points for quite a while, but was waiting on the Poly tower as I've wanted 1- and 2-bedrooms at Poly for even longer. However, I don't like resale restrictions at all, and I figured this may be our last chance to buy a direct, restriction-free contract at a reasonable price, at a resort where I really wanted more points anyway.
Now I'm crossing my fingers that Poly 2 is part of the existing association (for our current Poly points), but I'm not holding my breath.
