I had to call around to get the cash rates a few months back - I don't think the regular Disney reservation line had it - I think I had to call out to CA's call center, and then might have even had to call the resort.
Nunzia's rates sound familiar to be about right. I was specifically calling for a 2BR as we're splitting a stay with family and were using the cash rate as part of our method for establishing their "fair share" to pay in cash to us. We probably let them off with a bargain at $300/night.
