Last year I made my ressies in July for the HRH and got the E-rate. Of course, it was a brand new hotel that wasn't even finished, so there was a lot of availability. But when I called back in the fall, they couldn't add on a day for the E-rate.(Easter)
We're going back next Easter and are booked, but was told when I called again last week to call in October to see about the rates. I have a feeling they'll be out before then, and they'll go fast. I'm sure we'll all look out for each other and pass the word when it happens. That rate makes this a true bargain.
