*bump* I saw this thread a few weeks ago and glad that I did. I redeemed my first DSU yesterday and immediately after, I saw the full price for the suite on my reservation. However thanks to this thread, I just waited it out. I got about 3-4 more emails throughout the night and the price seems fixed now. (Which is great b/c I got a great BRG rate that is about $90/night cheaper than a regular room anyways.)
