The 2007 AAA rates are not out yet, but they should be soon. The 2006 AAA rates were released on June 30, 2005, so I would expect the 2007 ones to be announced any day now. (I called CRO a few days ago to make my 2007 room-only ressie & the CM said the same thing -- check back soon because she was expecting the AAA rates to be out this month.)
Hope this helps with your planning!
