The poly did have 2 nights available a few hours ago I believe it was 5/22 - 5/24 garden view.
You've just got to keep calling and/or checking the website. When I initially tried to apply the AP code to my reservation for the Poly I was told nothing available and on top of that there was nothing available for my dates except for the GF. I went ahead and booked GF for the entire 10 days of our stay. I check the website every morning, afternoon, and evening and so far I have been able to get WL courtyard view for 5 nights and Comtemporary MK View for 5 nights. We are going to do a split stay this time because DH has always wanted to try WL and I've always wanted to stay at the Comtemp with an MK view and we've already stayed at the GF once before and weren't that crazy about it. BUT, I'm still checking and if the Poly becomes available we will likely change our ressies again. The Poly is our favorite and it's hard to stray from home, LOL..
