while they may be booking up reservations, I think what's really happening is that many of those reservations are getting cancelled by people who have also cancelled there vacations. In May, we saw people getting walk-ups at every restaurant we went to, including CRT on Friday evening, Cali Grille on Saturday (of Memorial Weekend, even) and Le Cellier on Thursday actually had several empty tables the entire time we were there (like from 5:15 until when we left around 6:30.) When I booked these in February 2008, they supposedly were among the last available times for those nights.
