I'd like to hear the answer to this also. This board, and friends who went, said last weekend was pretty crowded. All I know about next weekend is, I called CRO yesterday to see if we could add Saturday to the beginning of our reservation (we were planning on arriving on Sunday originally) and we were able to add a room for Saturday night at Riverside, with an AP rate, with no problem. So, I'm holding out hope this weekend and next week will be a little slower.
Edited to add, I waited until last week to call for PS's and I also haven't had any problems getting them within 10 minutes of the requested time. I'm taking all of this as signs for optimism!
