We booked in advance for this past trip in March. I believe the prices for 2003 were out in late July or early August of 2002.
Good luck to a fellow early planner.
I was just told by a CM at CRO that they will not be out until the end of summer, or as late as Sept./Oct. although you can book a room now (but you would have to pay the 2004 rate when it comes out).
