The 2007 rates came out mid-August, 2006 and the 2008 rates came out mid-August, 2007. I was able to book a room only reservation in June, 2007 (for June, 2008) but was told that the rates would be adjusted as soon as the 2008 rates came out. I went ahead and booked so that I could hold our room (we had our hearts set on Wilderness Lodge). As soon as the official 2008 rates came out, I canceled the room only and booked a package.
