Nope, you may have to be a bit flexible with times or consistently stalk what you want when you want, but you should be able to get most of your to-do list.
I was just able to snag a Le Cellier dinner ADR for the first week of March this week.
Be sure to read up on the new cancellation policy before making your ADRs, you'll have to give your credit card for many of the popular restaurants now.
